Solve the problem.A rocket tracking station has two telescopes A and B placed 1.7 miles apart. The telescopes lock onto a rocket and transmit their angles of elevation to a computer after a rocket launch. What is the distance to the rocket from telescope B at the moment when both tracking stations are directly east of the rocket telescope A reports an angle of elevation of 22° and telescope B reports an angle of elevation of 56°? Round to the nearest hundredth of a mile.
A. 3.76 mi
B. 1.14 mi
