(6) Two kids are flying a kite with a string of 50 meters long. If the kids are 35 meters apart, how high is the kite off the ground? What formula should you use to solve?
Length of the string when in air (c) = 50 meters
The distance of kids apart (b) = 35 meters
The height of the kite off the ground = (a) ?

Use a² + b² = c² to solve. (50)² + (35)²=a²
Use c² - b² = a² to solve. (50)² - (35)² = a²
Just guess!
The correct formula to use is a² = c² - b²:
a² = (50)² - (35)²
a² = 2500 - 1225
a² = 1275
The height of the kite off the ground is approximately √1275 meters.
