Question

Solve for x. Round your answer to the nearest tenth if necessary.

Answer 1

Answer: x= 17.5

Explanation:
9^2 + 15^2= 81 + 225 =306
And the square root of 306 is 17.49 and you ask for it to be rounded to the nearest tenth so it will be 17.5.

Answer 2

x ≈ 17.5

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 = 9² + 15² = 81 + 225 = 306 ( take square root of both sides )

x =
`√(306)` ≈ 17.5 ( to the nearest tenth )
