A boy is flying two kites at the same time. He has a = 350 ft of line out to one kite and b = 450 ft to the other.

Question

A boy is flying two kites at the same time. He has a = 350 ft of line out to one kite and b = 450 ft to the other. He estimates the angle between the two lines to be 30°. Approximate the distance between the kites. (Round your answer to the nearest foot.)

??? ft

Answer 1

a² = b² + c² - 2bccosA

a² = 3502 + 4502 - 2(350)(450)cos(30)

The rest is on you.
