Question

Two cars leave the same parking lot, with one heading north and the other heading east. After several minutes, the northbound car has traveled 1.3 miles, and the eastbound car has traveled 6.4 miles. Measured in a straight line, how far apart are the two cars? If necessary, round to the nearest tenth.

Answer 1

Given a=5 and b=12,
c = 13
∠α = 22.62° = 22°37'12" = 0.39479 rad
∠β = 67.38° = 67°22'48" = 1.17601 rad
area = 30
perimeter = 30
