If an angle is acute, an angle supplementary to it is (always, sometimes, or never) acute

Given a: b and b: c, find a: b: c. write the ratio in simplest form. a: b=6: 10 and b: c=21: 33

Two angles are complementary. the larger angle is 36 more than the smaller angle. what is the measure of the larger angle?
