An altitude is drawn from the vertex of an isosceles triangle, forming a right angle and two congruent triangles. As a result, the altitude cuts the base into two equal segments. The length of the altitude is 13 inches, and the length of the base is 8 inches. Find the triangle’s perimeter. Round to the nearest tenth of an inch.

The **perimeter** of the **triangle** is 35.0 inches

We should know that **perimeter** of an object is the distance round the very object. the triangle has three sides, then the perimeter of the **trianggle** is the sum of the three sides.

Hence the altitude forms a right angled triangle, there are two **right angled triangles**.

Using the Pythagoras theorem, let the two sides of the triangle be x and y

X²=13²+4² (the altitude divided the base into 2)

x²=169+16

x²=185

Taking the **square root** of both sides

x=[tex]\sqrt{185}[/tex]

x=13.6 inches

For the length y

Use the same **Pythagoras** theorem

X²=13²+4²

x²=169+16

x²=185

x=13.6 inches

The perimeter is 8+13.6+13.6 = 35.2 inches

Therefore, the perimeter of the **triangle** to the nearest tenth is 35.0 inches

the rescue center currently has 9 snow geese each goose gets 16 oz of seed's there is 1,656 seeds in all how many days of food until the shelter runs out

**Answer:**

A soultion is provided that makes assumptions about missing information.

**Step-by-step explanation:**

The statement ". . . each goose gets 16 oz . . ." is missing some information about a time frame. Is it 16 oz per day, week, month? The question cannot be answered without this information.

We also don't know the relationship between the number of seeds and ounces. Is 16 oz 1 seed, 10 seeds, 1000 seeds? Again, we cannot solve this without additional information.

To add some insight how to solve the problem, lets make two assumptions:

**Assume 16 oz/week.** We can write this as a conversion factor: (16 oz food)/(1 snow goose).

**Assume 10 seeds/oz.**

The Rescue Center has 1,656 seeds in total.

(1,656 seeds)

Each snow goose gets 16 oz of seeds a week. That is (16 oz)*(10 seeds/oz) = 160 seeds/week per goose.

There are 9 geese, so they consume (9 geese)*(160 seeds/week/goose) = 1440 seeds/week

There are 1,656 seeds. At 1,440 seeds/week, they will last (1,656 seeds)/(1,440 seeds/week) = 1.15 weeks.

So b:)

**Step-by-step explanation:**

What are the zeros of FX x2 5x6?

The** zeros** of **function** f(x) = x2 - 5x + 6 are 3 and 2.

We can calculate the zeros of a **polynomial** using the **quadratic equation.**

The equation is:

x = [-b ± √(b2 - 4ac)] ÷ (2a)

In this case,

a = 1,

b = -5, and

c = 6.

Substituting these** values into the equation**, we get:

x = [-(-5) ± √((-5)2 - 4(1)(6))] ÷ (2(1))

Simplifying further, we get:

x = [5 ± √1] ÷ 2

The **solution **of the given** system of equations** 8x+3y=5 and 3x-2y=5 is x = 1 and y = -1

In this question we have been given a **system of equations**.

8x+3y=5 ..........(1)

and 3x-2y=5 ..........(2)

We need to find the **solution **of the given system of equations.

As right hane side of both equations is equal, we equate LHS of both equations.

so, we get,

8x + 3y = 3x - 2y

⇒ 8x - 3x = - 2y - 3y

⇒ 5x = - 5y

⇒ x = - y .............(3)

By substituting x = - y in **equation **(1), we get,

8 ( - y ) + 3y = 5

⇒ - 8y + 3y = 5

⇒ - 5y = 5

⇒ y = - 1

Substitute above **value **of y in equation (3)

⇒ x = - (- 1)

The sum of the **supplementary angles** is 180°

Thus,

The supplement of the angle 120° is 180°-120°=60°

The supplement of the angle 56° is 180°-56°=124°

The supplement of the angle 29° is 180°-29°=151°
