Question

8 squared plus x squared = 17 squared solve for x

Answer 1

x ≈ 15

Explanation:

using Pythagoras' identity in the right triangle

a² + b² = c²

with a = 8, b = x , c = 17

8² + x² = 17²

64 + x² = 289 ( subtract 64 from both sides )

x² = 225 ( take square root of both sides )

`√(x^2)` =
`√(225)`

x = 15
