Answer:
The answer to your question is e =
Step-by-step explanation:
Data
Ellipse = 36x² + 4y² = 9
e = ?
Formula
e = c/a
Process
1.- Convert the equation of the ellipse to the canonical form
36x² + 4y² = 9
- Divide by 9 both sides
36/9x² + 4/9y² = 9/9
4x² + 4/9y² = 1
x² /(1/4) + y² / (9/4) = 1
b² = 1/4 b = 1/2
a² = 9/4 a = 3/2
2.- Find c
a² = b² + c²
c² = a² - b²
Substitution
c² = 9/4 - 1/4
Simplification
c² = 8/4
c² = 2
c= 
3.- Find the eccentricity
e = 
e =
The exterior angle at the intersection of the tangent and secant has a measure that is half the difference between the intercepted arcs.
... ((10x+20) -80)/2 = 2x+15
... 5x -30 = 2x +15
... 3x = 45
... x = 15
So, the unknown arc to the right has measure
.. 10x + 20 = 10·15 +20 = 170
And the arcs of the circle total 360°.
... 80 + z + 170 = 360
... z = 360 - 250 = 110 . . . subtract 250 from both sides
The appropriate choice for the value of z is
... B. 110
