A triangle is 180°. So you can do:

3.2n + 6.4n + 2.4n = 180 Simplify

12n = 180

n = 15 Now that you know the value of n, you can plug it into each individual angle/equation

∠X = 3.2n plug in 15 for n

∠X = 3.2(15)

∠X = 48°

∠Y = 6.4(15)

∠Y = 96°

∠Z = 2.4(15)

∠Z = 36°

An ellipse has a vertex at (4,0), a co-vertex at (0,3), and a center at the origin. Which is the equation of the ellipse in stan

bekas [8.4K]

ANSWER

$\frac{ {x}^{2} }{ 16} + \frac{ {y}^{2} }{ 9} = 1$

EXPLANATION

The given ellipse has a vertex at (4,0), a co-vertex at (0,3), and a center at the origin.

The equation of an ellipse with vertices on the x-axis and center at the origin is:

$\frac{ {x}^{2} }{ {a}^{2} } + \frac{ {y}^{2} }{ {b}^{2} } = 1$

The ellipse has vertex at (4,0) , hence a=4.

Also the co-vertex is at (0,3) , b=3

We substitute the values into the equation to get:

$\frac{ {x}^{2} }{ {4}^{2} } + \frac{ {y}^{2} }{ {3}^{2} } = 1$

$\frac{ {x}^{2} }{ 16} + \frac{ {y}^{2} }{ 9} = 1$
