Question

Find the value of x. Round to the nearest tenth. The diagram is not drawn to scale.

Answer 1

x ≈ 8.4 cm

Explanation:

Using the tangent ratio in the right triangle, that is

tan35° =
`(opposite)/(adjacent)` =
`(x)/(12)`

Multiply both sides by 12

12 × tan35° = x, thus

x ≈ 8.4 cm ( to the nearest tenth )
