Answer:
20 degrees
Step-by-step explanation:
Let's label the angles:
The one near 150 degrees is A.
The one near 50 degrees is B.
The ? is C.
To find A:
180 - 150 = 30
A = 30 degrees
To find B:
180 - 50 = 130
B = 130
To find C:
All angles in a triangle add up to be 180 degrees so:
130 + 30 = 160
180 - 160 = 20
C = 20 degrees
