<A = 124

Step-by-step explanation:

Remark

This figure has 7 angles. Therefore it can have 5 lines drawn from 1 vertex to all the other vertexes.  That gives you 5 triangles. See the diagram below to see the result of what I have just described. The sum total of all the interior angles is  5 * 180 = 900

Equation

Add the seven given angles from your figure to equal 900

(9x - 2) + (10x + 2) + 165 + 100 + (5x + 83) + (12x + 18) + 138 = 900

Solution

Now add all the like terms on the left together.

So this simplifies to

36x + 504 = 900                        Subtract 504 from both sides

36x + 504 - 504 = 900 - 503    Do the subtraction

36x = 396                                   Divide by 36 on both sides

x = 396/36                                  Do the division

x = 14                                          

Answer

But you want angle A.

<A = 9x - 2 = 9*14 - 2 = 126 - 2 = 124

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
