**Given:**

The figure of a trapezium.

**To find:**

The measures of missing angle [tex]m\angle K, m\angle M[/tex].

**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]

[tex]m\angle M=93^\circ[/tex]

Similarly,

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

[tex]51^\circ+m\angle K=180^\circ[/tex]

[tex]m\angle K=180^\circ-51^\circ[/tex]

[tex]m\angle K=129^\circ[/tex]

**Therefore, [tex]m\angle M=93^\circ[/tex] and [tex]m\angle K=129^\circ[/tex].**

how many solutions will this quadratic equation x^2+8x+16 has?

hii i think it’s 3 i’m not sure tho bestue

**Answer:**

one solution

**Step-by-step explanation:**

to find out how many solutions a quadratic equation (with the equation ax²+bx+c) will have, we need to find the discriminant, which is b²-4ac

first, we can label the coefficients as a, b, and c

a=1 (1 is in front of x²)

b=8

c=16

now substitute into the formula

D=(8)²-4(1*16)

D=64-64

D=0

the discriminant is 0

when the discriminant is 0, that means the quadratic equation only has **one **solution.

Hope this helps!

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°

Step-by-step explanation:

In the expression 2x + y - 4, the coefficient of y is...

**Answer:**

1

**Step-by-step explanation:**

If a term does not have a written coefficient, then the coefficient is one.

This is because 1(y) = y

**Answer:**

1

**Step-by-step explanation:**

there is an "understood" 1 as the coefficient of any blank variable

but it is useless to write since anything times 1 is just the same number ..... (i.e: y *1= y...same as 5 * 1= 5)

use the substitution method to solve

3x + 2y=12

y=2x -1

**Answer:**

1. y=2

2. y= - 2

**Step-by-step explanation:**

Thats my answer hope it helps

**Answer:**

**the solution is : (2 , 3)**

**Step-by-step explanation:**

hello : here is an solution

3x + 2y=12.....(*)

y=2x -1.....(**)

put the value for y in (*) :

3x + 2(2x-1)=12

3x+4x-2 = 12

7x =14

so : x =2

but : y=2x -1

y =2(2)-1 = 3

**the solution is : (2 , 3)**

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

1. Write the expression:

(1.75 x 10^)(1.2 x 102)

2. Rearrange the expression: (1.75 X 1.2)(104 x 103)

3. Multiply the coefficients: (2.1)(104 x 103)

4. Apply the product of powers: 2.1 x 104

The rocket ship will travel 2.1 x 109 miles. What is the value of y in the solution?

y = 1

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

Can someone please help me I’ll give brilliant thingy

**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.

Cheers.

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)

= 1

**Hence the required answer is 1**
