Question

In the right triangle shown in the diagram below, what is the value of x to the nearest whole number? X 30° 24

Answer 1

Answer:

21

Explanation:

To be able to find the value of x, we have to take the cosine of 30 degrees;

$\begin{gathered} \cos 30=\frac{x}{24} \\ x=24\cos 30 \\ x=20.78 \\ \therefore x=21\text{ (to the nearest whole number)} \end{gathered}$
