1 answer:
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:
The actual length of the living room is <u>60 square feet</u>.
Step-by-step explanation:
Given:
A blueprint of a house shows a living room that is 15 square inches.
If the blueprints is 1 inch : 4 feet.
Now, to find the actual square foot of the living room space.
Let the actual square foot of the living room be
The length of the room in the blueprint is 15 square inches.
The blueprint of the house is 1 inch : 4 feet.
So, 1 inch is equivalent to 4 feet.
Thus, 15 inches is equivalent to
Now, to use the cross multiplication method to get the actual square foot of the living room:
Therefore, the actual length of the living room is 60 square feet.
