                   1.  The length of a string between a kite and a point  on the ground is 90
                       meters. If the string makes an angle θ with the ground level such that
                       tan θ = 15/8. How high is the kite? Assume that there is no slack in
                       the string
                   2.  A tower stands vertically on the ground. From a point on the ground,
                       20 m away from the foot of the tower, the angle of elevation of the top
                       the tower is 60°. What is the height of the tower?
                   3.  On the same side of a tower, two objects are located. When observed
                       from the top of the tower, their angles of depression are 45° and 60°.
                       If the height of the tower is 150 m, find the distance between the
                       objects.
