Answer:

Part 1: 25 feet long

Part 2: 8 feet high

Step-by-step explanation:

A^2 +B^2 =C^2

C is the hypotenuse which you are finding for part 1.

You are finding B for part 2.

Part 1:

15^2 + 20^2 = C^2

225+400=C^2

625=C^2

Sqrt(625)= C

25=C

Answer for Part 1 is 25 feet long.

Part 2:

6^2 + B^2 = 10^2

36 + B^2 = 100

Subtract 36 from both sides.

B^2 = 64

B= sqrt(64)

B= 8

Answer for Part 2: 8 feet high
