Question

For the following right triangle, find the side length x. Round your answer to the nearest hundredth.

Answer 1

x ≈ 15.62

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 = 12² + 10² = 144 + 100 = 244 ( take square root of both sides )

x =
`√(244)` ≈ 15.62 ( to the nearest hundredth )
