X = 82
a corresponding angle of 82 is also the vertical angle to x. This makes then equal.

- Perimeter of rectangle = 40 inches
- Length of rectangle = 15 inches
Let the required Breadth of rectangle be 'x' inches
Perimeter of rectangle is calculated by the given below formula :
- Perimeter = 2(Length + Breadth)
Now, substitute the given values in above formula :
→ 40 = 2(15 + x)

The equation that best models this situation would be: y=40+30x
When x =2, f(x) = 128
When x = 4, f(x) = 8
The changing rate is
This changing rate represents the decrease of the number of contestants as the competition approaches the final.
