The angle of elevation of the sun is 20 degrees. At the same time,how long is the shadow cast by a building 50 meter high?

Answer 1

You would start off by setting up the equation as follows:

tan20=50/x (You would use tan because of the chief, SOHCAHTOA tan is opposite over adjacent.

multiply by x on both sides leaving you with
xtan20=50

Divide by tan 20.

Your answer would be 137.37 meters

Answer 2

tan20=50/x
xtan20=50
50/tan20
137.37 meters

Answer 3

When the angle of elevation of the sun is 61°, the building casts a horizontal shadow of 50 meters . How high is the building
