Foci (focus points) of an ellipse
Two points inside an ellipse that are used in its formal definition. See Ellipse definition.
Try this Drag any orange dot. As you reshape the ellipse, note how the two focus points (F1 and F2) move.

An ellipse has two focus points. The word foci (pronounced 'foe-sigh') is the plural of 'focus'. One focus, two foci.
The foci always lie on the major (longest) axis, spaced equally each side of the center.
If the major axis and minor axis are the same length, the figure is a circle and both foci are at the center.
Reshape the ellipse above and try to create this situation.
Note how the major axis is always the longest one, so if you make the ellipse narrow,
it will be the vertical axis instead of the horizontal one.

Hey there!
First; let us understand that there are 360° in a full circle.
<em>This is what we are representing. </em>
We need to find a way to multiply to get the answer.
<u>36% of 360 = 0.36</u>, therefore we need to make 0.36 x 360
<u>Multiply 0.36 x 360 </u>
Therefore, we <u>get 129.6°</u>
<h3>EXACT Answer:</h3>
<u>129.6°</u>
<h3>Rounded answer: </h3>
<u>130°</u>
Answer:
you plug in the number that x is into the formula then solve it from the formula
Step-by-step explanation:
Standard form of a quadratic equation: ax^2 + bx + c = 0
3x - 4 = -x^2
x^2 + 3x - 4 = 0
Hope this helps!
