Jonas Bennett · Answer 1

The distance from the top of the tree to the shadow is 40.8 ft.

From the given figure:

cos theta = adjacent/hypotenuse

cos 36 = 33/H

H=33/cos 6 = 40.8 ft

In order to fully understand the problem, it is best to sketch it. Sketching the system, we will see that the system forms a triangle where the angle of elevation is 36 degrees. We are asked to find the hypotenuse. We can use a trigonometric function. It should be noted that one of the sides should also be given in order to calculate the hypotenuse. Trigonometric functions that can be used are:

sin (theta) = opposite / hypotenuse

cos (theta) = adjacent / hypotenuse
