Question

an electric post was hit by a lightning and was broken. the broken part makes a right triangle with the ground forming a 20° angle with the other part. the topmost part which is on the ground is 15 meters from the base, how tall is the post before it was hit by a lightning

Answer 1

Assuming the 20° is at the top of the triangle,
let they hypotenus (the fallen over part of the pole) be x
cos20° = 15/x
x = 15/cos20 = 15.96

height of original pole = 15 + 15.96 = 30.96 metres

Answer 2

height = [15 m / tan(20º)] + [15 m / sin(20º)]
