angle d and e for linear pair and measure of angle e equal 3m angle d find the measure of each angle and the measure of the complement of angle d

Review you notes for the definition of linear pair. It means that d+e = 180°
d + 3d = 180
d = 45
e = 135
So, since complementary angles add to 90°, what's d's complement?
