Answer:
Explanation:
To find the measure of angle B in the triangle, we can use the fact that the measures of the angles in a triangle always add up to 180 degrees.
We know that the measure of angle A is 112 degrees and the measure of angle C is 40 degrees, so we can set up the following equation:
A + B + C = 180
Plugging in the known values, we get:
112 + B + 40 = 180
Solving for B, we find that the measure of angle B is 28 degrees.
Therefore, the missing angle of the triangle is 28 degrees.
