I think it might be 43° because since the line is going through the middle, it would be 180-47-90=43 (the 90 came from the right angle)
hope this helps! :)
Answer: x =5.5
x+3=8.5
subtract “-3” from both sides
x = 5.5

Step-by-step explanation:
Answer:
Options A and B.
Step-by-step explanation:
An ellipse is represented by the equation
We have to find the foci of the given ellipse.
Ellipse having equation
Then center of this ellipse is represented by (h, k) and foci as (c, 0) and (-c, 0).
And c is represented by c² = a² - b²
So we co relate this equation with our equation given in the question.
a = √625 = 25
b = √49 = 7
and c² = (25)² - (7)²
c² = 625 - 49 = 576
c = ±√576
c = ±24
Now we know center of the ellipse is at (-5, 7) so foci can be obtained by adding and subtracting x = 24 from the coordinates of the center.
Center 1 will be [(-5+24=19), 7] ≈ (19, 7)
Center 2 will be [(-5-24=-29), 7] ≈ (-29, 7)
Therefore, options A and B are correct.
