Answer:

x = 9

Explanation:

using Pythagoras' identity in the right triangle

the square on the hypotenuse is equal to the sum of the squares on the other 2 sides , that is

x² + 6² = (
√(117)

x² + 36 = 117 ( subtract 36 from both sides )

x² = 81 ( take square root of both sides )

x =
√(81) = 9
