Question

Phythagorean Theorem

Answer 1

Answer:

12 feet

Step-by-step explanation:

1. We know that the hypotenuse is 15 ft and the base is 9, know we can apply it into the pythagorean theorem

a = side of right triangle  = 9 ft.

b = side of right triangle  = ?

c = hypotenuse                = 15 ft.

a^2 + b^2 = c^2

2. Rearrange the equation so b is equal to a and c

b^2 = c^2 -  a^2

3. Apply into the equation with the information we know

b^2 = 15^2 -  9^2

4. Simplify by multiplying the square root of 15 and 9

b^2 = 15^2 -  9^2

b^2 = 225 -  81

5. Simplify by subtracting

b^2 = 144

6. Find the square root of 144

b= √(144)

b = 12
