a) a is complementary to 70° so it is 20° b) a and b are complementary so b is 70° c) c is complementary to b so it is 20° d) d is complementary top c so it is 70° e) e is a linear pair with d so it is 110°
3) supplements add to 180 so 180-122=56 4) p and q are supplementary so q=180-90=90 5) a and t are complementary sup both are less than 90. that means the supplement out both is >90 and thus obtuse
