Answer:
C) 6
Step-by-step explanation:
From the given data we can find the constant of proportionality by dividing The number of people by number of cars.
Constant of proportionality =
Taking any point from the table will give the same constant of proportionality as they are proportional quantities.
Constant of proportionality =
This can be written as 6 people per car.
For 10 cars, number of people will be ==60 people.
The value of x is 8 from the diagram given.
<h3>How do you calculate the sides of similar triangles?</h3>The corresponding sides of a similar triangle are said to be in proportion if and only if the corresponding angle are also equal.
To calculate the side of line x (|x|), we have to determine the ratios of the corresponding sides as:
x = 120/15
x = 8
Therefore, we can conclude that the value of x is 8.

Answer:
x ≈ 6.2 cm
Step-by-step explanation:
using the cosine ratio in the right triangle
cosΘ = , that is
cos39° = =
( multiply both sides by 8 )
8 × cos39° = x , then
x ≈ 6.2 cm ( to 1 dec. place )
