1. One angle is three times as great as an

other angle. The sum of the degrees in

both angles is 180°. How many degrees

are in each angle?

one angle is 45 degrees and the other is 135

Step-by-step explanation:

I do this weird becuase I visualize the angles. I take 180 and since I know that one angle is 3 times as large as the other, then 180 can be broken up by the value of the small angle 4 times, 180 / 4 = 45 I reserve that single angle value of 45, and add the other 3 up, 45 + 45 + 45 = 135

I hope that makes sense
