Answer 1

you would have to use the law of sines. Or the law of cosines

Answer 2

cosine I belive

Answer 3

\[\cos X=\frac{ 11 }{ 20 }\]

Answer 4

then this is where I get tuck

Answer 5

from there you would divide both sides by cosine

Answer 6

if you do it on a calculator make sure you are in degrees not radians

Answer 7

divide by cosine what though

Answer 8

actually i think you would arc sin the 11/20

Answer 9

yea because I need to do the inverse to get the angle

Answer 10

ya thats right i think

Answer 11

i put in cos^-1 (11/20)=56.6329870308
