Answer:
127°
Explanation:
I remember a teacher gave me a solution to solve these types of questions.
choose only one corner and draw lines from that Corner to the rest of the corners to form triangles.
for example, in this question, I choose 120°. 1 line to 125°, 1 to 133°, one to 112°. you can't draw any straight lines to the rest of the corners.
now you have 4 triangles. and the sum of the angles of each triangle, is 180°. so, the sum of the angles of this Irregular hexagon is 4×180=720°.
now:
112+133+120+100+128+x=720
593+x=720
x=720-593
x=127°
i know it seems a little complicated, but if you read it carefully, you'll probably understand.if anything is unclear, ask freely.
