Answer:
24
Explanation:
If you see the big picture, you would realise ABC is actually a triangle so that means all the angles in it add up to 180°. The angle nearest point B is 90° since it is a right angle, the point nearest A is 66°, so you are able to find then angle nearest C, which is the angle of elevation.
Angle of elevation = 180° - 90° - 66°
= 24°
