Question

Find the value of x for which m||N






A.


31




B.


33




C.


39




D.


41

Answer 1

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

Answer 2

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

Answer 3

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

Answer 4

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

Answer 5

for M//N 75=3x-18

Answer 6

so it would be 31?

Answer 7

yes

Answer 8

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
