...please help this is due in an hour an she didn't explain it to us...if you can help in any way, even if it just an explanation, i will love you so much

Actually Welcome to the Concept of the Angles.

11) Vertically Opposite Angles, 6x= 30 , thus x= 5

12) Adjacent Angles, 4+5x+x+2 = 180

= 6+6x= 180 => 1+x= 30 , x= 29

13) Right Angle, 2x+1+x+2=90 ==> 3x+3=90 => x+1= 30

=> x=29

14) Right Angle, 3x+1+4+2x = 5x+5= 90 ==> x+1 = 18

=> x=17

15)Vertically Opposite Angles are same,

y+23= 63 , thus y= 63-23 ==> y= 40

2x-17 = 234 ( remaining angle after subtraction of 63 for two times)

2x= 251 , thus x= 125.5

16)Linear pair, 47-2x+x^2+32 = 180

=> 79-2x+x^2= 180

= x^2-2x = 101

=x(x-2) = 101

17)

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
