Answer:
Step-by-step explanation:
cos(11) = .9816271834 so now what we have is
.9816271834 = sin(x)
Find x by taking the inverse sin of .9816271834 by hitting your 2nd button and the sin button. What you have on your screen now is
[tex]sin^{-1}([/tex] Now enter the decimal after the parenthesis and hit your equals button. You should get x = 78.999999999 so we'll just round that to 79
