A boy is flying two kites at the same time He has a 350 ft

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.)

Solution

given a = 350 ft

b = 450 ft

s^2 = 350^2+450^2-2*350*450cos30

s = 228 ft
