Adjacent angles are 2: 4 to find the degree measure of the larger angle.

Adjacent angles are angles that move on one straight line, they have a common “side” and in total they are equal to 180 °
To find the degree measure of a larger angle, you need to break the problem into parts:
2 + 4 = 6 pieces fall on 2 adjacent corners
180 ÷ 6 = 30 ° falls on 1 part
A larger angle takes 4 parts, which means: 30 × 4 = 120 °
Answer: 120 °
