In the triangle determine the value of c

The answer is A: 8.6

Step-by-step explanation: In this case, the side you're trying to figure out is the opposite and the side measurement given is the hypotenuse.

This means that out of the sin, cos, and tan we will be using sin.

Sin(Ф)= opposite/hypotenuse

Plug in the numbers you know: Sin(35)=x/15

Take the 15 to the other side to get x by itself

Then plug into your calculator 15Sin(35)=x

This gives you 8.6
