Answer:
80
Step-by-step explanation:
These angles are alternate exterior angles and alternate exterior angles are equal when the lines are parallel
12x+8 = 13x+2
Subtract 12x from each side
12x+8-12x = 13x+2-12x
8 = x+2
subtract 2 from each side
8-2 =x
6 =x
Find the measure of the angle
12x+8
12*6+8
72+8
80
Answer:
The answer to your question is below
Step-by-step explanation:
Data
Center = (0, 0)
Vertex = (13, 0)
Focus = (12, 0)
Process
From the data we know that it is a horizontal ellipse.
1.- Calculate "a", the distance from the center to the vertex.
a = 13
2.- Calculate "c", the distance from the center to the focus
c = 12
3.- Calculate b
Use the Pythagorean theorem to find it
a² = b² + c²
-Solve for b
b² = a² - c²
-Substitution
b² = 13² - 12²
-Simplification
b² = 169 - 144
b² = 25
b = 5
4.- Find the equation of the ellipse
or ![\frac{x^{2} }{169} + \frac{y^{2}}{25} = 1](https://tex.z-dn.net/?f=%5Cfrac%7Bx%5E%7B2%7D%20%7D%7B169%7D%20%2B%20%5Cfrac%7By%5E%7B2%7D%7D%7B25%7D%20%3D%201)

The lines are reciprocal because they cross to form an X. Also 4/5 is the reciprocal of 5/4
If the total for four late fees were fifty six dollars, then to find the amount for one, we divide the total by the amount of late fees.
So it'll be 56 / 4 which will equal to 14 dollars.
One late fee is equaled to fourteen dollars.
