ok as long as you get it done its all good lol

Answer 8

okay i think i got it but it could be wrong considering i havent done this in a while

Answer 9

1st you would solve for cosine since you know the hyp and are looking for the adjacent
\[\cos 33= x/8.2\]
but you have to get rid of the 8.2 so you use inverse \[(8.2/1)\cos 33=x/8.2 (8.2/1)\]
cancels the 8.2 on the side with te x and leaves you with the x and you get \[(8.2)\cos33\approx6.87=x\]

Answer 10

so then solve for the missing angle which ends up being 57
