Two angles are supplementary and the ratio of the angels is 1:4. what is the value of smaller angle?
Correct Answer: 36 degree
Explanation:
As we know that the angles are supplementary so sum of angles will be 180 degree.
Let us assume that the ratio factor is r.
According to question,
Angles are supplementary and have a ratio of 1:4.
r + 4r = 180
⇒ 5r = 180
⇒ r = 180/5
⇒ r = 36
