Let c be the hypotenuse and use the Pythagorean theorem. 8^2 + 15^2 = c^2 64 + 225 = c^2 289 = c^2 17 = c
a=-2 4b=-2 --> b=-1/2 c=8 (-2)(-1/2)(8)(3)= 24
using the pythagorean thereom. a^2 + b^2 = c^2 in which a and b are your legs and c is your hypotenuse 8^2 + 15^2 = c^2 289=c^2 17 is the hypotenuse
(c + 8)(c - 8)= c^2 - 64
The eccentricity of a planet's orbit can be calculated using the formula e c/a, where c is the distance between the center of the orbit and the focus, and a is the length of the semi-major axis of the orbit.

Eccentricity is the measure of how much the conic section diverges into its circle form. One of the formulas for eccentricity is e=c/a this formula can be used to get the eccentricity of the ellipse.
8 = 2 cubed
The eccentricity of that ellipse is 0.4 .

Let c be the hypotenuse and use the Pythagorean theorem. 8^2 + 15^2 = c^2 64 + 225 = c^2 289 = c^2 17 = c
Mercury has an orbital eccentricity most similar to the moon's orbital eccentricity, which is about 0.2056. Mercury's eccentricity is approximately 0.206.
