Answer 2

Which missing side?, there's two..

Answer 3

theres suppose to be an X under the 22 degrees.. sorry :l and that's the side you have to find ill re draw it

Answer 4

You could use: \[\LARGE cos(22)=\frac{x}{12}\]
Multiply by 12 \[\LARGE 12(cos(22))=x\]
I think that's how you do it.

Answer 5

yeaaa thing is idk what cos is ...

Answer 6

cos22? Or just what cos is suppose to find?

Answer 11

Oh, well stuff like cos(22) you're suppose to plug into a calculator, not solve mentally.

Answer 12

ik that part

Answer 13

Well, when you multiply 12 and cos(22), that's your answer..

Answer 14

so it should look like 12(cos22)=x?

Answer 15

If you're looking for exact answers, yes.

Answer 16

thx

Answer 17

The approx. for the missing side is 11.13

Answer 18

my other triangle ad 19 for one side and 30* for an angle my missing side came out to be \[\frac{ 19\sqrt{3} }{ 2}\]
