Answer 3

I would say you are correct ;)

Answer 4

explain? @563blackghost

Answer 5

i think i got it

Answer 6

i hope im correct

Answer 7

R is vertical to 76...The `Vertical Angle Theorem` States that two angles that are vretical from each other and are created from two intersecting angles are congruent. So R equals 76.

With that said we see we also know of 38.....we see that the angle adjacent to R (not Q) is created by the parallel lines and the intersecting ray that makes angle 38 so we would say that angle is 38 degrees. Now we also apply the `Vertical Angle Theorem` to that so the angle across from 38 is congruent. So we know that R equals to 76 and the adjacent angle (not Q) is 38. Now a straight line has a total degree of 180 so we would add the two known angles and subtract from 180 to find Q.

\(\Large\bf{180-(76+38)=Q \rightarrow 180 - 114 = 66 = Q}\)

So Q equals 66.

Answer 11

i think it is 11

Answer 12

5x and 9x+26 have to be supplementary angles, so use that to find x.

Answer 13

is it 11?

Answer 14

Yes.

Answer 16

i believe its D?

Answer 17

Well I agree with the Same-Side Interior Angles Theorem but not so much with g being parallel to h. Since `angle 1 and angle 2 are Same side interior angles` then they are supplementary due to j and k being parallel.

Answer 18

so should be A?

Answer 19

Yes ma'am/sir ;)

Answer 22

is it 28???

Answer 23

Yes it is :)

Answer 24

could you explain?

Answer 25

It is 28 due to the fact that x and 28 are `alternate interior angles`. These two angles are on opposite sides of transversal but they are contained in the two parallel lines.

Answer 26

http://prntscr.com/cwyfwc thanks, 2 more

Answer 27

does it have something to do with the 2 lines in the middle not being parallel?? like the angles

Answer 28

Oh I remember these problems :D I looked at @ganeshie8 explanation for this one before it might help you :) Im sorry but I must take my leave.
