Answer: 270°, 630°, -450°, -810°
<u>Step-by-step explanation:</u>
positive: -90 + 360 = 270
270 + 360 = 630
negative: -90 - 360 = -450
-450 - 360 = -810

If you subtract another 2π, you will end up with a negative value. The question asks for the smallest positive value.
The distance from the center to where the foci are located exists 8 units.
<h3>How to determine the distance from the center?</h3>The formula associated with the focus of an ellipse exists given as;
c² = a² − b²
Where c exists the distance from the focus to the center.
a exists the distance from the center to a vertex,
the major axis exists 10 units.
b exists the distance from the center to a co-vertex, the minor axis exists 6 units
c² = a² − b²
c² = 10² - 6²
c² = 100 - 36
c² = 64
c = 8
Therefore, the distance from the center to where the foci are located exists 8 units.
