The expressions in the figure below represent the measures of two angles. find the value of x. f||g.

a. 17
b.-16
c. 16

So before we find the value of x, let us remember that the sum of two angles is 180 degrees. Now, let us solve for x.
180 = 7x + 2x + 36
180 = 9x + 36
180-36 = 9x
144 = 9x <<divide both sides by 9 
and the result would be 16.
Therefore x =16.
