Question

A and B are two point on level ground , both due south of a flagpole. The angle of elevation of the top of the flagpole is 60 degree from A and 45 degree from B . If A is 20m from the foot of the flagpole, find/AB/. Answer it

Answer 1

B is equal to the height (h) of the flagpole (isosceles right triangle)

h / A = tan(60º) ... h = 20 m * tan(60º)

AB = [20 m * tan(60º)] - 20 m = 20 m * {[tan(60º)] - 1}

Answer 2

Pls i need a diagram to illutrate this question
