Find a value of x that satisfies the equation cos11°=sin(x).

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

 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
