Question

In PQR, the measure of R=90°, the measure of Q=71°, and RP = 40 feet. Find

the length of QR to the nearest tenth of a foot.

Answer 1

13.8

Explanation:

tan Q = opposite = 40

adjacent x

Tan 71 = 40 x tan 71 = 40

x tan 71 = 40

tan 71 tan 71

x = 40 = 13.7731 = 13.8 (rounded to the nearest tenth)

tan 71
