Akite string is 220 feet long from the kite to the ground. the string makes a 45 degree angle with the ground. about how high off the ground is the kite?

The best way to solve these types of questions is to draw a diagram. In this case, we can draw a right triangle with the kite string as the hypotenuse. Since a right triangle has a right angle, and the other angle is 45 degrees, we can deduce that the last angle is also 45 degrees because the sum of all angles in any triangle is equal to 180. 

There is a special ratio with right angles that have the angles 45, 45, and 90. The ratio tells us that the hypotenuse is  times as large as the sides. 

220 = x
220/2 = x
110 = x

The kite is 110 ft. from the ground.
