I found sin which was 1/2. The book says feta is 30 degrees. But how does the value of sin contribute to this and where does thirty degrees come from?

**Reiny**, Sunday, December 6, 2009 at 9:22pmYou are correct to say that sin(theta) = 1/2

we also know that sin 30 = 1/2

so isn't theta = 30 ?

Make sure your calculator is set to degrees.

enter

200 / 400

=

press 2ndF or INV, whichever your calculator uses

press SIN

=

you should get 30 degrees.

BTW, who is this feta guy? Did you mean theta, the Greek letter?

I think feta is some kind of cheese.
