Answer:
88°
Explanation:
Let's look at the triangle inside. Two angles are given already. A triangle is 180°. So the other one on the inside is 180-(38+50) = 92°
The side of∠1 is a straight angle.We have found 92 so m∠1 is (180-92) = 88
m = 92 degrees
you know all angles of a triangle add up 10 180 degrees.
