The shadow of a vertical tower is 65 ft long when the angle of elevation of the sun is 35 degrees. Find the height of the tower

Answer 1

clear case of right-triangle trig

height/65 = tan 35°
height = 65tan35°
= ....

Answer 2

Find the angle of elevation of the sun when a tower 83 m high casts a shadow 20 m long.

Answer 3

Application of surds in solving triangles(trigonometrical ratios of special triangles)calculate the height of a tree whose shadow is 20m shorter when the angle of elevation of the sun is 60° than when the angle of elevation is 30°
