ANSWER
37°
Step-by-step explanation
The angle of elevation of the sun is the angle through which one has to raise the head to see the sun.
When a 24 feet tree casts a shadow of 36 feet, we can obtain a right triangle as shown in the diagram to help us calculate the angle of elevation of the sun.
Let x be the angle of elevation of the sun, then


Hence, the angle of elevation of the sun is 37° to the nearest degree.
