what is sin of 30 degrees, what is cos of 5(pie)/6, convert 7(pie)/6 radians to degrees, tan of 225 degrees, which angles is the sin >0, which angles is the sin<0, and which 2 angles are the sin and cos equal. PLEASE NEED HELP BADLY​

Do you have a photo?

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.

Ci think but i'm not entirely sure so..
