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:
Step-by-step explanation:
The area of a rectangle can be found with the formula
, where
is the length of the rectangle and
is the width.
From the given problem statement, we know that
and
, so we can fill in those values in the formula anbd solve for
to get the width:


Divide both sides by
to isolate
by itself:


The answer to this is 16.
