A damsel is in distress and is being held captive in a tower. Her knight in shining armor is on the ground below with a ladder. When the knight stands 10 feet from the base of the tower and looks up at his precious damsel, the angle of elevation to her window is 60°. How long does the ladder have to be? And how high is the window to reach the damsel?

10/x = cos60°
x = 20 ft

h/20 = sin60°
