Can someone please help me with this because I don’t get it

Answer 1

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

Answer 2

Explanation:

the sum of the two interior angles equals that exterior angle

121+40=161
