to find y, you subtract 180-99 since y+99 is equal to 180

anonymous · Answer

y and z are ulterior angles where the addition of the two would also give you 180 degrees, so z = 180-y which would give you 99 degrees

anonymous · Answer

and finally, z + (3x-18) = 180
so rearrange to get your value of x

anonymous · Answer

so would i set it up as 99 + (3x-18)=180?

amilapsn · Answer

for M//N 75=3x-18

anonymous · Answer

so it would be 31?

amilapsn · Answer

yes

anonymous · Answer

no, it would be 33 @chriswhenever ,
99 + (3x-18) =180
so (3x-18) = 180 -99
     3x-18 = 81
        3x = 81 +18
        3x = 99
          so x = 33
