Atree casts a shadow that is 24 feet in length. if the angle of elevation is 30 degrees, which of the following best represents the height of the tree?

13.856 feet

Step-by-step explanation:

The height of the tree and its shadow forms a right angle. Together with the line joining the pit of the shadow and the tree make a right triangle.

We can use the trigonometric ratio tangent to find its height.

tan = opposite/adjacent

tam 30° = x/24

height = 24 × tan 30°

           = 24 ×0.57735

           = 13.856 feet

the functions have the same rate of change i think. i narrowed it down to this answer and "the rate of change of tour 1 is greater" but i got it wrong using that answer so im assuming its the answer above. (this is a question i also answered from the iready site if anyone needs a reference)
