Question

supplementary angles are angles whose measures have a sum of 180degree complementary angles have a sum of 90degrees find the measure of an angle whose supplement is 10degrease more than twice its supplement let 90-x equal the degree measure of its supplement write and solve and equation!

Answer 1

180-x=10+2(90-x)
180-x=10+180-2x
x=10
complementary=80
supplementary=170=10+2*80
