OpenStudy (freckles):
supplementary means they add up to 180 deg
OpenStudy (triciaal):
as above so (3 x + 28) + (4 x -2) = 180 group like terms , simplify and solve for x
OpenStudy (anonymous):
ok, so now i have 7x+26=180. is that right?
OpenStudy (triciaal):
after you have x you can find 3 x + 28 one angle and 4 x -2 the other
OpenStudy (triciaal):
yes

OpenStudy (triciaal):
x = 22 now find the angles
