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

42

Step-by-step 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=(8)/(12) \\ x=\sin ^(-1)((8)/(12)) \\ x=41.81 \\ \therefore x=42^(\circ)\text{ (to the nearest degre}e) \end{gathered}`
