**Jai**, Wednesday, June 15, 2011 at 8:07amlinear 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~ :)
