Question

What is the answer for this and please explain ?

Answer 1

Hey there! :)

You have to use the Pythagorean Theorem: a² + b² = c²

a = 15
15² = 15 × 15 = 225

b = 20
20² = 20 × 20 = 400

225 + 400 = 625

√625 = 25

c = 25 feet

Hope this helps :)

Answer 2

The Pythagorean Theorem: (a² + b² = c²)
1. Substitute the known values
20² + 15² = c²
400 + 225 = 625
2. Solve
625 = c²
Divide and solve for both side, simplify and you get:
Answer: C = 25
