FIND THE MEASURES OF ANGLE 1 AND ANGLE 2 IF MEASURE ANGLE 1=3X12 MEASURE ANGLE 2=7X+2 AND ANGLE 1 AND ANGLE 2 FORM A LINEAR PAIR

linear pair means the sum of the angles equal 180 degrees. therefore,
3x  12 + 7x + 2 = 180
10x  10 = 180
10x = 190
x = 19
finally, substituting this back to angle 1 and 2:
Angle 1: 3(19)  12 = 45 degrees
Angle 2: 7(19) + 2 = 135 degrees
hope this helps~ :)
