Maureen measured a house and its lot and made a scale drawing. The scale she used was
PIT_PIT [208]

The most appropriate choice for unitary method will be given by-

Length of driveway  in the drawing is 3 inch

What is unitary method?

Unitary method is the method in which value of a single unit can be calculated from the value of a multiple unit and value of a multiple unit can be calculated from the value of a single unit.

Sometimes value of single unit is less than value of multiple unit

For example - cost of food and quantity of food

Sometimes value of single unit is more than value of multiple unit

For example- Number of men and time taken by those men to do a work

Here,

Scale used by Maureen is 1 inch = 8ft

Actual length of house's driveway = 24 feet

8 ft of room is equal to 1 inch on scale

1 ft of room is equal to \frac{1}{8} inch on scale

24 feet of room is equal to \frac{1}{8} \times 24 inch on scale

24 feet of room is equal to 3 inch on scale

Length of driveway  in the drawing is 3 inch

What is the value of x? Please provide an explanation, thanks!
Novosadov [1.4K]

Answer:

28

Step-by-step explanation:

What you do is add up 42 and 76, then you subtract that from 180, because all triangles add up to 180. the subtracted amount is what z equals. Then since its a straight line you know it adds up to 180. You add z (62) and 90 because its a right angle. then you subtract 180 by 152 to get 28.
