Answer:
Consider the two trees as perpendiculars on the ground forming a right triangle, where the distance between their bases is the base (B), the distance between their tops is the Hypotenuse (H) and difference between their lengths is the perpendicular (P).
Hypotenuse, H=17 m
Perpendicular, P= distance between their lengths =28−20=8 m
Thus, By Pythagoras Theorem,
