The ratio of the measure of two supplementary angles is 3:7. Find the measure of each angle. ____°,_____°

anonymous · Answer

supplementary means?

anonymous · Answer

Supplementary angles are angles whose sum is 180 degrees.
Let the first angle be 3x and the second angle be 7x. 3x+7x = 180, x= 18.

The ratio of the measure of two supplementary angles is 3:7. Find the measure of each angle. 54°,128°

kartik, nice job...

anonymous · Answer

Sorry the second angle is 126*  not 128* . Typing mistake.

anonymous · Answer

Supplementary means 180 degrees and Complementary means 90 degrees..

So you are given with ratios so take the advantage of that:

Let the one angle by 3x and other be 7x:

So their sum must be supplementary or we can say 180:

$$3x + 7x = 180$$

$$\implies 10x = 180$$

Find x by dividing 10 both the sides..

Then find the two angles by $3x$ and $7x$..
