Please help, my teacher has barely taught us anything on this stuff. I'm SOOO confused. Your help would really help me not be so confused on how to do this. Please help!

The key is SOHCAHTOA

anonymous · Answer

This means that the sine is found with opposite over hypotenuse, cosine is alternate over hypotenuse, and tangent is opposite over alternate.

anonymous · Answer

To find sinA, you take the side opposite angle A (8sqrt3) and put it over the hypotenuse (16). Then, simplify 8/16, giving you (sqrt3)/2.

With part B, you use the 30-60-90 formula

anonymous · Answer

Ohh okay. Wow thank you I'm so stupid. I understand how to get that part now. Thank you!

anonymous · Answer

This makes it easy to find the answer, 30.

anonymous · Answer

You're not stupid, things just make more sense when explained. :)

anonymous · Answer

What exactly is the 30-60-90 formula?

anonymous · Answer

This diagram shows it. Basically, a 30-60-90 triangle is a type of triangle where you can use certain equations to always get the side lengths. In this case, x=8.

anonymous · Answer

Ohh okay

anonymous · Answer

Would angle B then be 30? @CasidyCat

anonymous · Answer

Yep! :)
