Question

What is the value of x

Answer 1

x ≈ 19.2 units

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 , then

x² + 19² = 27²

x² + 361 = 729 ( subtract 361 from both sides )

x² = 368 ( take square root of both sides )

x =
`√(368)` ≈ 19.2 ( to the nearest tenth )
