Hello, we cannot see the ellipse equations.
The eccentric of an ellipse is given by:
Assuming the equations are:
Then a²=25 and b²=16
The eccentricity is:
If the ellipse has equation,
then the this time, we have a=5 and b=3.
This means that:
Answer:
Option (3)
Step-by-step explanation:
By applying cosine rule in the triangle ABC,
BC² = AC² + AB² - 2(AC)(AB)cosA
5² = 3² + 7²- 2(3)(7)cosA
25 = 9 + 49 - 42cos(A)
25 = 58 - 42cos(A)
cos(A) =
A =
A = 38.21°
A ≈ 38°
