Answer:
16)
- q / 12 = sin 20
- q = 12 sin 20
- q = 4.1
- p / 12 = cos 20
- p = 112 cos 20
- p = 11.3
17)
- x / 44 = tan 39
- x = 44 tan 39
- x = 35.6
- 35.6 / y = sin 39
- y = 35.5 / sin 39
- y = 56.4
18)
- 14 / b = sin 57
- b = 14 / sin 57
- b = 16.7
- a / 16.7 = cos 57
- a = 16.7 cos 57
- a = 9.1
Plug in the 1/2 where the a’s are answer is -3
