Answer:

161

Step-by-step explanation:

the sum of the two interior angles equals that exterior angle

121+40=161

answer: x= 161

explanation: in the triangle angles 59 and 40 are already shown, so u just need to subtract them from 180. 180-40-59=19. since the line=180° you need to subtract 19 from 180. 180-19=161
