h/30 = 2/3
or maybe
h/30 = 3/2
just use corresponding sides to get the correct ratio.
In the future, be specific, as in
Triangle ABC is similar to triangle DEC. Then name the lengths and angles you know.
trigonometry
Determine the distance from Point A to the top of the tree. (The tree in the big triangle makes a 90 degree angle with the ground and the smaller triangle is a similar triangle. The bottom of the tree is 30m from point A) *
point a to the trunk of the tree is 30 m
Triangle a has a base of 3m and the other side is 2 m
