Answer:
58 degrees
Explanation:
We know that angles on a straight add up to 180 degrees. Therefore:
To find the angle at the top of the triangle do 180-112 = 68
To find the angle at the right side of the triangle do 180 - 126 = 54
We know that angles in a triangle add up to 180 degrees. Therefore:
To find m do 180 - (54 + 68) = 58
