Answer:
After Two Hours.
Step-by-step explanation:
A simple way to do it is to:
1. Add 50+55, it is equal to 105. This is after one hour, so we know that it's more than this.
2. Add 50+55 to 105, This is after two hours, and we get 210, so we know that it has to be equal to 2 hours.
Let the two numbers be x and x + 40, then
x + x + 40 = 180
2x = 180 - 40 = 140
x = 140/2 = 70
Therefore, the measures of the two angles are 70° and 70 + 40 = 110°
