Question

The center pole of a tent is 8 feet long, and a side of the tent is 12 feet long as shown in the diagram below. 12 ft 8 ft A If a right angle is formed where the center pole meets the ground, what is the measure of angle A to the nearest degree?

Answer 1

Answer:

42

Explanation:

Let x represent the measure of the angle A.

To find x, we have to take the sine of x;

$\begin{gathered} \sin x=\frac{8}{12} \\ x=\sin ^{-1}(\frac{8}{12}) \\ x=41.81 \\ \therefore x=42^{\circ}\text{ (to the nearest degre}e) \end{gathered}$
