Question

Use trigonometric ratios to find the unknown values. (Round to the nearest tenth)

Answer 1

Answer:

b = 7.4

c = 7.2

b = 68

Step-by-step explanation:

Use trigonometry ratio,

1) tan 39° = 6/b

b = 6/tan 39° = 7.4

2) sin 44° = 5/c

c = 5/sin 44° = 7.2

3) cos 41° = b/9

b = 9 cos41° = 68
