It’s 81 since 180-127 is 53, and if you add 53 to 46 it’s 99,
And 180-99 Is 81.
Answer:
3
Step-by-step explanation:
The distance from one focus, to any point on the ellipse and then to the other focus = length of major axis
So, 10 + dashed line = 13
Therefore, dashed line = 13 - 10 = 3
F(x) = ax + b
f(x) = 5x - 2
So: a =5
tg α = a
tg α = 5
α ≈ 78,5 °
One option for the answer would be -(9+9)
