<h3>Further explanation </h3>Comparison is an effort to compare two or more objects in terms of shape or size, or number
Proportional Comparisons are comparisons of two or more numbers where one number increases, the other numbers also increase
Can be formulated
so that if:
x = 2
then
While the reversal value comparison is the comparison of two or more numbers where one number increases, the other number decreases in value
Can be formulated
so that if:
x = 2
then
The size of a crowd who can see the parade can be calculated using the principle of proportional comparison
- 1. We calculate the ratio of people and areas that can be occupied
The question stated that 10 people occupy a square measuring 5 feet by 5 feet
means the area occupied by 10 people = 5 ft x 5 ft = 25 ft²
so the ratio is :
- 2. We calculate the area of the road that can be occupied when viewing the parade
Because there are 1/4 mile section of a parade route and 5 feet deep on both sides of the street, the total area
1 mile = 5280 ft
1/4 mile = 1320 ft
Total area = 1320 ft x 5 ft (deep) x 2 (both sides of the street) = 13200 ft²
Then the comparison of points 1 and 2 can be used to calculate the total number of people who saw the parade
Total people =
Total people = 5280 (C)

Answer:
Option C is the best choice.
Step-by-step explanation:
✺ First , Let's know about Corresponding angles :
- A pair of interior and exterior angles which lies to the same side of a transversal.
- Remember that the corresponding angles are always equal.
- The easiest way to think of corresponding angles is the 'F - Pattern'.
✎ Now, In our case , x ° and ( 3x - 70 ) ° are corresponding angles. Set up an equation and solve for x.
{ Move 3x to left hand side and change it's sign )
{ Combine like terms }
{ Divide both sides by -2 }
The value of x is 35°
Now, As we are asked to find the value of m ABC , replace the value of x :
Therefore , m ABC = 35°
And we're done !
Hope I helped!
