Question

Instructions: Find the missing side. Round your answer to the nearest tenth.

Answer 1

x ≈ 74.3

Explanation:

Using the tangent ratio in the right triangle, that is

tan22° =
`(opposite)/(adjacent)` =
`(30)/(x)` ( multiply both sides by x )

x × tan22° = 30 ( divide both sides by tan22° )

x =
`(30)/(tan22)` ≈ 74.3 ( to the nearest tenth )
