Manpreet is standing 8.1 m from a flagpole. His eyes are 1.7 m above ground. The top of the flagpole has an angle of elevation of 35 degrees. How tall is the flagpole?
The CN tower is 553m tall. From a position on one of the Toronto islands 1.13km away from the base of the tower, determine the angle of elevation, to the top of the tower. Assume that your eyes are 1.5 m above ground.

first one
h = 1.7 + 8.1*tan(35) = 7.4 meters
second one
alpha = atan((553-1.5)/1130) = 26 degrees
