Question

I'm stupid and don't know how to do this... Please help..

Answer 1

Your not stupid, you just don't know everything yet and guess when you know everything....never.  but you.ll get better.  

Angles across from each other like 7 and 5 are called vertical angles and they are the same (92)

angles beside each other are called linear pairs and if you add them together then are 180.  so 5 + 8 = 180  and 5 is 92 so

92 + ∠8 = 180

∠8 = 180 -92 = 88
