x = 152.

Figure out the angles of the insides of the triangle and then you'll have your answer:

First angle = (supplementary) 180 - 85 = 95

Second angle = (supplementary) 180 - 123 = 57

95 + 57 = 152

152 = the measure of angles one and two

Find the third angle

180 - 152 = 28

Angle x and angle three (28) are supplementary angles so subtract to find x:

180 - 28 = 152
