HELP PLEASE!!!What is the measure of /_BAC?

100°

130°

**Answer:**

<BAC = 80

**Step-by-step explanation:**

All triangle angles equal 180

<BAC = x

x + 50 + 50 = 180

x + 100 = 180

x = 180 - 100

x = 80

The sum of two numbers is 0. Twice the smaller number subtracted from 3 times the larger number is 10. Let x represent the larger number and y represent the smaller number. Which equations represent this situation?

**Answer:**

y= -x

y= 3/2 -5

**Step-by-step explanation:**

The sum of two numbers is zero.

x + y = 0

y = -x

Twice the smaller number subtracted from 3 times the larger number is 10.

Let x represent the larger number and y represent the smaller number.

Twice the smaller number: 2y

3 times the larger number: 3x

Twice the smaller number subtracted from 3 times the larger number is 10.

3x - 2y = 10

-2y = -3x + 10

y = 3/2 x - 5

The equations are:

y = -x

y = 3/2 x - 5

A 9-foot (ft) ladder and a 4-foot ladder are leaning against a house. The two ladders create angles of the

same measure with the ground. The 4-foot ladder has a height of 3.8 feet against the house.

Help please!!

**Answer:**

The 9-foot ladder would have a height of 8.55 ft against the house

**Step-by-step explanation:**

The angles made by the 9-foot ladder and 4-foot ladder that are leaning against the house is **71.8 degrees**.

The situation forms a right angle triangle.

What is a right angle triangle?A** right angle triangle** has one of its angles as 90 degrees. The sides and angle can be found using trigonpometric ratios.

Therefore, the 9 foot and the 4 foot ladder forms the same angle.

The 4 foot ladder forms a 3.8 ft height against the wall.

Hence,

**sin ∅ = opposite/ hypotenuse**

sin ∅ = 3.8 / 4

∅= sin⁻¹ 0.95

∅ = 71.8051276612

∅ = 71.8°

Therefore, the angles made by the 9-foot ladder and 4-foot ladder that are leaning against the house is **71.8 degrees**.

The three angles of a quadrilateral are 55,73,105 what is the fourth angle

**Answer:**

**127**°

**Step-by-step explanation:**

In a quadrilateral, sum of four angles is 360°.

Consider the fourth angle x.

so,

55° + 73° + 105° + x = 360°

x = 360° - 233°

x = 127°

The quadrilateral must equal 360°. You already know 3 of the sides so add them up and subtract it from 360.

360-233= 127

The fourth angle is 127°

360-233= 127

The fourth angle is 127°

The speed of a truck, s, must be no less than 34 miles per hour.

**Answer:**

s = ≥34

**Step-by-step explanation:**

The **speed **of the truck, s, must be no less than 34 miles per hour

is s ≥ 34.

What are inequalities and their types?Inequality is a relation that **compares **two numbers or other mathematical expressions in an unequal way.

The symbol a < b indicates that a is smaller than b.

When a > b is used, it indicates that a is bigger than b.

a is less than or equal to b when a notation like a ≤ b.

a is bigger or equal value of an is indicated by the notation a ≥ b.

Given, The speed of a truck, s, must be no less than 34 miles per hour.

Therefore, The speed of the truck must be** greater than or equal to** 34 miles per hour.

So, The inequality that represents this context is,

Which of the following is equivalent to log 2 (c)⋅log c (2)

**Answer:**

1

**Step-by-step explanation:**

According to law of indices

log a b = 1/ log b a

hence log c (2) = 1/log 2 (c)

log 2 (c)⋅log c (2)

= log 2 (c)⋅ 1/log 2 (c)

= log 2 (c)/log 2 (c)

**Solution:**

In the given figure [tex]JK\parallel ML[/tex].

If a transversal line intersect the two parallel lines, then the same sides interior angles are supplementary angles.

[tex]m\angle J+m\angle M=180^\circ[/tex] (Supplementary angles)

[tex]87^\circ+m\angle M=180^\circ[/tex]

[tex]m\angle M=180^\circ-87^\circ[/tex]

What is the y-intercept to (-2,1) (3,-6)

**Answer:**

(0,-9/5)

**Step-by-step explanation:**

You can use the equation y=mx+b to solve

First you have to find the slope (m)

You can do this by using the equation y2-y1=x2-x1

(-6-1)/(3--1)= -7/5

**m=-7/5**

You then use the slope to find out b or the "y-intercept"

I am using the point (-2,1) to substitute

(1)=-7/5(-2)+b

**-9/5=b**

y=-7/5x-9/5

Check (3,-6):

(-6)=-7/5(3)-9/5

-6=-21/5- 9/5

-6=-6 true

A telephone pole casts a 32-foot shadow, while a street sign next to the pole casts a 12-foot shadow. If the

telephone pole is 40 feet tall, what is the height of the street sign?

12

**Answer: **The height of street sign = 15

**Step-by-step explanation:**

At the same time, the angle made by the light on each object is the same.

Pole and street sign both standing vertical to the ground.

So triangle made by both of them are similar

The sides of similar triangles are proportional,

[tex]\dfrac{\text{height of street sign}}{\text{height of pole}}=\dfrac{\text{Length of the shadow made by street sign}}{\text{Length of the shadow made by pole}}\\\\\dfrac{\text{height of street sign}}{40}=\dfrac{12}{32}\\\\\text{height of street sign}=\dfrac{12}{32}\times40=15[/tex]

Hence, **the height of street sign = 15**

Complete question is;

A rocket ship is travelling at an average speed of 1.75 × 10⁴ miles per hour. How many miles will the rocket ship travel in 1.2 × 10² hours?

1. Write the expression: (1.75 × 10⁴)(1.2 × 10²)

2. Rearrange the expression: (1.75 × 1.2)(10⁴ × 10²)

3. Multiply the coefficients: (2.1)(10⁴ × 10²)

4. Apply the product of powers: 2.1 × 10^(y)

The rocket ship will travel 2.1 × 10^(y) miles. What is the value of y in the solution?

Answer:

Distance travelled by rocket ship = 2.1 × 10^(6) miles

y = 6

Step-by-step explanation:

1. The written expression;

(1.75 × 10⁴)(1.2 × 10²)

2. The rearranged expression is;

(1.75 × 1.2)(10⁴ × 10²)

3. Let's multiply the coefficient which is the first bracket to get;

2.1(10⁴ × 10²)

4. Applying the product of powers means we will add the powers of ten which are 4 and 2.

Thus; 2.1(10^(4 + 2)) = 2.1 × 10^(6) miles

Comparing to 2.1 × 10^(y), we have;

y = 6

**Answer:**

Yes, the shapes are similar. Note, the angles are equivalent and the sides are scales of each other satisfying the requirements for similarly.

**Step-by-step explanation:**

For a shape to be similar there are two conditions that must be met. (1) Must have equivalent angles (2) Sides must be related by a scalar.

In the two triangles presented, the first condition is met since each triangle has three angles, 90-53-37.

To test if the sides are scalar, each side must be related to a corresponding side of the other triangle with the same scalar.

9/6 = 3/2

12/8 = 3/2

15/10 = 3/2

Alternatively:

6/9 = 2/3

8/12 = 2/3

10/15 = 2/3

Since the relationship of the sides is the scalar 3/2 (Alternatively 2/3), then we can say the triangles meet the second condition.

Given that both conditions are satisfied, then we can say these triangles are similar.

Note, this is a "special case" right triangle commonly referred to as a 3-4-5 right triangle.
