Question

The area of the rectangular piece of plywood ( shaded region ) is 10.2 m^2. Find the angle of elevation.

Answer 1

5.63 degrees to the nearest hundredth.

Explanation:

Length of the plywood

= area / width

= 10.2 / 2

= 5.1 m

Sin x = 0.8 / 5.1 where x is the agle of elevation

sin x = 0.09804

x = 5.626 degrees
