Answer:
The measure of angle 2 is 45 degrees
Step-by-step explanation:
Mathematically, when two angles are supplementary, the sum of these angles will be equal to 180 degrees
Let the measure of angle 2 be x
The measure of angle 1 is 3 times this and that will be 3 * x = 3x
The sum of both will be 180
x + 3x = 180
4x = 180
x = 180/4
x = 45
