Atree casts a shadow that is 18 feet, in length. if the angle of elevation is 28, which of the following best represents the height of the tree?

The first step for this problem should always be to draw out the triangle so that you can right down the angles and side lengths. Afterward, you can use SOHCAHTOA to find the height of the tree. You would use tangent. The equation you would use is tan(28°)x/18. After solving for x, you will find the answer which is approximately 9.57 feet.

Hope this helped :)
