Question

what is the approximate value of sin C ( can anybody solve this) ??

Answer 1

you need to know sohcahtoa.

Answer 2

sin x= opp/hyp, cos x= adj/hyp, tan x= opp/adj; S=O/H, C=A/H, T=O/A

Answer 3

so for angle C, the opposite side is 7, the hypotenuse is 17.46

Answer 4

therefore, sin C = opp/hyp, which means sin C = 7/17.46

Answer 5

we find the angle through the arc operations; arcsin(7/17.46)=C

Answer 6

all you need to do at this point is plug into your calculator and get a value. considering the answer choices, i'd say you should put your calculator in radians, so you get a radians angle.
