Answer 6

so you know two sides. do you know how to find an angle by the side or a side by an angle?

Answer 7

Yes, I think I would use tan.

Answer 8

to find the angle

Answer 9

alright, well i'll explain it an easier way. As you can see that one of the angles is 90 degrees and the side opposite of the angle is 45 cm or whatever. so that means the side is half of the angles degrees.

Answer 10

Alright.

Answer 11

so if you have that you just do the opposite to get an angle. so the angle that is opposite of 12, what would you get?

Answer 12

\[\cos ?=\frac{ 12 }{ 45 }\]

Answer 13

74 degrees

Answer 14

no, you would have to multiply it by 2 which is 24. You know what all the inside angles of a triangle adds up to right?

Answer 15

Yes.

Answer 16

alright so you have two of the angles and that's all you need to get the third. Go ahead and see if you can do it, if not i will still help
