Find the value of each trigonometric ratio to the nearest ten-thousandth

13) 0.9230

14) 0.8000

15) 0.3846

16) 1.3333

17) 0.7500

18) 0.2195

Step-by-step explanation:

sin = opp/hyp

cos = adj/hyp

tan = opp/adj

13) sin X = 36/39 = 0.923076923

14) cos X = 16/10 = 0.8

15) cos Z = 10/26 = 0.384615385

16) tan C = 40/30 = 1.33333333

17) tan C = 21/28 = 0.75

18) sin Z = 9/41 = 0.219512195

to find the perimeter, you add up all the lengths of the sides. in this case you would have to add up 18+22+40+80 which equals 160.
