A triangle lays on a straight line. the top corner of the triangle  is equal to 42 degrees. A is the bottom right corner if the exterior angle of A is 111 what A equal to? And what is B equal to?

A and B would equal 69 degrees. Because 180-111 would be equal to 69 then you would add 69 and 42 and would get 111 leaving the remaining angle to equal to 69 degrees.

https://helpingwithmath.com/finding-missing-angles/ Right click or highlight the text and us this URL to look at example one and tell me what the angle B is equal to.

The two triangles on the bottom are equal so A is equal to 35 degrees. So you add 35+35 and get 70, 180-70=110 so B is equal to 110 degrees.
