it is a 60,80,100 right triangle
draw from "vertex with right angle" to hypotenuse an altitude line
meaning line makes right angle with hypotenuse.
altitude has length of 48, and hypotenuse is divided by altitude
into lengths 36 (adjacent to 60 side) and 64 (adjacent to 80 side)
from similar triangles
60=√(36*100)
80=√(64*100)
48=√(36*64)
