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°.
Answer:
15 days
Step-by-step explanation:
Let x be the number of days needed for B to complete the job. Then x-5 is the number of days needed for A to complete the job.
In 1 day,
Hence, in 1 day both A and B complete of all work. A and B working together can do a work in 6 days. Then
Solve this equation:
If then
that is impossible. So, B needs 15 days to complete the work alone.
