Question

Could someone help me out with this ?

Answer 1

Answer:

15

Step-by-step explanation:

To find the hypotenuse of a right triangle, we can use the Pythagorean theorem

a^2 + b^2 = c^2,  where a and b are the legs and c is the hypotenuse

We know that a=12 and b = 12

9^2 + 12^2 = c^2

81 + 144 = c^2

225 = c^2

Take the square root of each side

sqrt(225) = sqrt(c^2)

15 =c

Answer 2

Answer:

c = 15

The length of the hypotenuse is 15.

Step-by-step explanation:

In order to find the hypotenuse, we would need to use the Pythagorean theorem.

The formula for the pythagorean theorem is:

$a^2+b^2 = c^2$

The numbers we have been given:

A = 9

B = 12

Input the numbers in our formula.

$9^2 + 12^2 = c^2$

Solve.

9 to the power of 2 is 81

12 to the power of 2 is 144

Add.

144 + 81 = 225

Find the square root of C.

$\sqrt{225} = 15$

Let's check our work.

$9^2 + 12^2 = 15^2$

Answer:

The length of the hypotenuse is 15.
