Answer:


\sin(50^o) = (3)/(c)

Explanation:

Given

See attachment for triangle

Required

Expression to solve c

To solve for c, we simply calculate the sine of angle at B

i.e.


\sin(50^o) = (Opposite)/(Hypotenuse)

This gives:


\sin(50^o) = (3)/(c)

Make c the subject


c = (3)/(\sin(50^o))

Right triangle ABC is shown. Which equation can be used to solve for c? 3 O sin(50%) = 3 3 m-example-1
