ANSWER
The smaller angle is
.EXPLANATION
Let the angles be
where y is the smaller angle.
Since they are supplementary, they will add up to 180°.
This implies that,
If one angle is 4 times the other, we can then write the following equation,
We put equation (2) into equation (1) to get,
We divide through by 5 to obtain,
This implies that,
Answer:
Divide: 7/12 : 3/10 = 7/12 · 10/3= 7 · 10 /12 · 3 = 70/36 = 35/18
To divide one fraction by another, invert (turn upside-down) the second fraction, then multiply.
