Two supplementary angles are in the ratio of 5 to 7. Find positive difference of the measure of the two angles. Do the same problem, only do it for complementary angles instead of supplementary angles.
They are in the ratio 5:7 so just assume 1 part of the ratio is x, which means 12x=180
15*2 is going to be the positive differance between the 2 angles so for #1 it is 30
Next one, just divide the answer to the previous question by 2 so 15
