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

Answer :

Answer:

13.8

Step-by-step 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
