I'm flying a model airplane at the end of a control line, the line is 17yd long and the plane is above a point

Question

on the ground that is 15 yd away from the controls. If the controls are held at a height of 1 1/2yd, how high is the plane off the ground?

Answer 1

hypotenuse = 17

adjacent = 15

opposite = b

pythagoras

b = √(17² - 15²) = 8

height = b + 1.5 = 9.5
