Answer:

121

Step-by-step explanation:

Number of sides = n = 7

Sum of all the interior angles = (n -2)*180 = (7-2) *180

= 5 *180

= 900

x + 125 + 119 +117 +145 + 133 + 140 = 900

x + 779 = 900

x = 900 - 779

x = 121

NEED HELP ASAP, WILL GIVE BRAINLIEST

Stella [2.4K]

Given:

The equation of circle is

$(x+3)^2+y^2=9$

To find:

The polar form of given circle.

Solution:

We have,

$(x+3)^2+y^2=9$

$x^2+2(x)(3)+(3)^2+y^2=9$ $[\because (a+b)^2=a^2+2ab+b^2]$

$(x^2+y^2)+6x+9=9$

Subtracting 9 from both sides, we get

$(x^2+y^2)+6x=0$

We know that, $x^2+y^2=r^2$ and $x=r\cos \theta$ .

$r^2+6(r\cos \theta)=0$

$r(r+6\cos \theta)=0$

$r=0$ and $r+6\cos \theta=0$

We know that, r is radius it cannot be 0. So,

$r+6\cos \theta=0$

$r=-6\cos \theta$

Therefore, the correct option is A.
