Question

The measure of angle 1 is 125 degrees what is the measure of angle 2?

Answer 1

Angles 1 is equal to angle 3. Together they add up to 250 degrees. All four angle have to add up to 360. So you do 360 - 250 to get 110 = angle 2 + angle 4. Since 2 and 4 are equal, you have to divide In half to get 55. Angle 2 = 55
