The formula for the total sum of the inner angles of the polygon is

Sn= (n-2) 180°

1) S6= (6-2) 180 = 4*180 = 720° In the hexagon all angles are equal

α= S6/6= 720/6= 120°

2) In each polygon the sum of the external angles is 360°

3) S5= (5-2) 180 = 540° than we can add up all angles

x+131+108+107+110=540 => x= 540-456= 84°

4) α = 360/5=72°

Good luck!!!

PLEASE HELP, 50 POINTS QUESTION IS IN THE PICTURE

artcher [175]

Answer:

$-\frac{50}{3}$

Step-by-step explanation:

Find dy/dx of the ellipse $25x^{2} +y^{2}=109$ at (2,3)

Using Implicit Differentiation

Differentiate both sides of the equation with respect to x

$25x^{2} +y^{2}=109$

$50x +2y\frac{dy}{dx}=0$

isolate the term dy/dx

$2y\frac{dy}{dx}=-50x$

$\frac{dy}{dx}=-25\frac{x}{y}$

Evaluate at point (2,3)

For x=2, y=3

$\frac{dy}{dx}=-25(\frac{2}{3})$

$\frac{dy}{dx}=-\frac{50}{3}$

Determine whether the graphs of y=-9x+11 and y=1/3x-12 are parallel, perpendicular, coincident, or none of these.

nirvana33 [79]

Answer:

None

Step-by-step explanation:

Parallel means exactly the same just lower or higher(same slope)

Perpendicular means they come together at a right angle, it is evident these do not

Coincident means directly on top of one another which they are not

Since it is none of these than the answer is obviously none of these ;)

I hope this helps u pls give a brainliest and a thx :)
