ANSWER

$( {x - 11)}^{2} + ( {y - 5)}^{2} = 16$

EXPLANATION

The given circle has center:

(11,5)

and

radius: 4

The equation of a circle with center (h,k) and radius , r is given in standard form as;

$( {x - h)}^{2} + ( {y - k)}^{2} = {r}^{2}$

We substitute the values into the formula to obtain,

$( {x - 11)}^{2} + ( {y - 5)}^{2} = {4}^{2}$

$( {x - 11)}^{2} + ( {y - 5)}^{2} = 16$

What is the value of y?

mojhsa [17]

<h2>QUESTION:- What is the value of y?</h2>

<h2>ANSWER:- </h2>

SUM OF ALL INTERIOR ANGLE = 180

$y + y + 72 = 180 \\ 2y + 72 = 180 \\ 2y = 180 - 72 \\ 2y = 108 \\ y = \frac{108}{2} \\ y = \frac{ \cancel{108}^{ \: \: \: \tiny{54}} }{ \cancel{2}} \\ y = 54 \degree$

DOES ANYONE UNDERTAND THIS? IF SO PLEASE HELP

Nana76 [90]

The sides must be equal otherwise BC and AD wouldn't be parallel. So
12x-6 = 2x+7
10x = 13
x = 13/10 = 1.3
