the answer is d) -9
because the total angle (angle fgh) is 104*
59*(angle cgh)+63*(angle fgc)=122*
then you take 122*-104*=18*
because angle fgh is only 104* and the x is being added to the 59 & 63, you already want your answer to be less than 122, so you would need a negative number, suggesting that you are subtracting the excess to get the resulting answer of 104
