Question

Triangle png What is the angle measure of angle B?

Answer 1

Since all the angles of a triangle combined equal 180, add the given degrees and did subtract them from 180.

40+112=152
180-152=28
B=28

Answer 2

`m\angle B = 28^(\circ)`

Explanation:

All angles in a triangle must add up to
`180^(\circ)`

We can solve for
`\angle B` using this knowledge

`\angle B + 40 + 112 = 180\\\angle B + 152 = 180\\\boxed{\angle B = 28}`

That is the answer
