sin13/20=sin142/x Cross Multiply x=54.7 sin13/20=sin25/x Cross Multiply x=37.5

SMALLER TRIANGLE

sin90/37.5=sin38/x Cross Multiply x=23 237-213=24 23+24=47f

We have calculated that the height of the tree is 47 feet tall.

The trigonometric concepts we used were law of sines and the Pythagorean theorem.
