Question

What is the value of x to the nearest tenth

Answer 1

x ≈ 24.7

Explanation:

Using the Sine rule in the triangle , that is

`(x)/(sin71)` =
`(15)/(sin35)` ( cross- multiply )

x × sin35° = 15 × sin71° ( divide both sides by sin35° )

x =
`(15sin71)/(sin35)` ≈ 24.7 ( to the nearest tenth )
