Answer:
The angles are <u>155°</u> and <u>25°</u>.
Step-by-step explanation:
Given:
Two supplementary angles are in the ratio of 31:5.
Now, to find the angles.
The sum of two supplementary angles = 180°
Let the ratio of the angles be .
So, according to question:
<em>Dividing both sides by 36 we get:</em>
So,
And,
Therefore, the angles are 155° and 25°.
