The interior angles of a 9-agon add up to (9 -2)*180° = 1260°. The sum of the given angles is
.. 1139° +x° = 1260°
.. x = 1260 -1139 = 121

The missing angle measure is 121°.

_____
The supplement of each interior angle is its corresponding exterior angle. The sum of exterior angles of any convex polygon is always 360°. Another way to approach this problem is to add the exterior angles.

find the formula for a rational function that satisfies all of the following. its x-intercept is (-3,0). it has a vertical asymp

Norma-Jean [14]

Let that be

$\\ \rm\Rightarrow y=\dfrac{a(f(x))}{g(x)}$

Two vertical asymptotes at -1 and 0

$\\ \rm\Rightarrow y=\dfrac{a(f(x)}{x(x+1)}$

If we simply

$\\ \rm\Rightarrow y=\dfrac{a(f(x)}{x^2+1}$

Denominator has degree 2
Numerator should have degree as 2 and coefficient as 3 inorder to get horizontal asymptote y=3 means the quadratic equation should contain 3x²
But there should be a x intercept at -3 so one zeros should be -3

Find a equation

3x²+9x

Find zeros

3x²+9x=0
3x(x+3)=0
x=0,-3

Horizontal asymptote

3x²/x²
3

So our equation is

$\\ \rm\Rightarrow y=\dfrac{3x^2+9x}{x(x+1)}$

Solve the system of equations

Kazeer [188]

Answer:

(3,4)

Step-by-step explanation:

x+y=7, where y=4, so therefore make x the subject and substitute y=4

x=7-y

x=7-4

x=3

therefore x=3, y=4.
