Question

For the following right triangle, find the side length x.
15

Answer 1

x = 17

Explanation:

`c^(2) = a^(2) + b^(2)`

`c^(2) = 8^(2) + 15^(2)`

`c^(2) = 64 + 225`

`c^(2) = 289`

`√(c^2) = √(289)`

`c = 17`

Answer 2

Answer: 17

Explanation:

Pythagorean Theorem

a^2+b^2=c^2

8^2+15^2=c^2

64+225=c^2

289=c^2

Now square both sides

x=17
