Question

For the right triangle shown, what is the sine of angle C?

Answer 1

first off is it clear that \(C=30\) ?

Answer 2

since the angles have to add up to \(180\) degrees, one is 90, one is 60, so the other one \(C\) must be 30

Answer 3

I know that; I just don't have a calculator...

Answer 4

so you are being asked for \(\sin(30)\)
do you know it?

Answer 5

lol
of course you do, you are on a computer!

Answer 6

wouldn't hurt to know that
\[\sin(30)=\frac{1}{2}\] however
also
\[\sin(60)=\frac{\sqrt{3}}{2}\] is a good one to memorize

Answer 7

i can't find a sin, cos, and tan calculator though.

but thank you!
