Question

150
50
Solve for missing angle

Answer 1

20 degrees

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
