Question

18. Find the length of the segment indicated. Round your answer to the

nearest tenth if necessary

Answer 1

x ≈ 6.2

Explanation:

Using Pythagoras' identity in the right triangle

x² + 17.1² = 18.2²

x² + 292.41 = 331.24 ( subtract 292.41 from both sides )

x² = 38.83 ( take the square root of both sides )

x =
`√(38.83)` ≈ 6.2 ( to the nearest tenth )
