Question

1) Find the value of x. Round to the nearest tenth.

Answer 1

x ≈ 12.9

Explanation:

Using the tangent ratio in the right triangle

tan35° =
`(opposite)/(adjacent)` =
`(9)/(x)` ( multiply both sides by x )

x × tan35° = 9 ( divide both sides by tan35° )

x =
`(9)/(tan35)` ≈ 12.9 ( to the nearest tenth )
