Question

What is the length of the hypotenuse of a right triangle with legs that are 7 feet and 10 feet respectively?

Answer 1

Use the Pythagorean Theorem:
a² + b² = c² (note: c is the hypotenuse)
7² + 10² = c²
49 + 100 = c²
149 = c²

`√(149) = \sqrt{c^(2) }`

`√(149) = c`
12.2 ≈ c

Answer 2

7² + 10² = c² where c = hypotenuse

49 + 100 = c²
149 = c²

c = √149 feet
