Given that ∠s and ∠t are supplementary angles, and they are in the ratio of 7:3
Total ratio = 7 + 3 = 10
The sum of 2 supplementary angles is 180 degrees.
Therefore, we have:
m∠s + m∠t = 180
Let's find measure of angle s, using the formula:
[tex]\frac{ratio\text{ of angle s}}{\text{total ratio}}\ast180[/tex][tex]\frac{7}{10}\ast180\text{ = }\frac{1260}{10}\text{ = 126}[/tex]Therefore, the value for m∠s = 126 degrees
ANSWER:
m∠s = 126 degrees
