Question

Use right triangle DCB to find the trig values for angle D.

sinD =

cosD =

tanD =

Answer 1

sin D= opp./hyp. = 35/37
cos D= adj./hyp. = 12/37
tan D= opp./ adj. = 35/12

Answer 2

Answer: sinD = 0. 9459

cosD =0. 3243 tanD=2. 917

Explanation:

From the figure above;

opposite = 35

adjacent = 12

hypotenuse = 37

sin D = opposite/hypotenuse

sinD = 35/37 = 0. 9459

cosD = adjacent/hypotenuse

= 12/37 = 0. 3243

tanD = adjacent/opposite

= 35/12 = 2. 9167
