Question 33937
Draw the picture.
The problem probably assumes there is no slack in the string.
You have a right triangle near the kite holder.
The 30 degree angle is at his hand.
The hypotenuse of the right triangle is the 200 ft. of string
The side opposite the 30 degree angle is (1/2)100=50 ft.
But the boy is holding the string 5 ft. above the ground.
Therefore the height of the kite is 50 + 5 = 55 ft.
