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

21

Step-by-step explanation:

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

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