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.

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

step-by-step explanation:

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
