Question

Is Vertical Angles Theorem 105 degrees? If not, then how many degrees is it?

Answer 1

It isn't clear what you mean here?

Vertical angles are equal, and part of proving that involves showing that both vertical angles are supplementary to the angle next to (i.e. in between) them. Supplementary means the angles add to180 degrees.

Answer 2

I'm supposed to find the measure of 9 and 10.

Answer 3

Are those two lines crossing somewhat vertically supposed to be parallel? They don't look like it. Is there any more info in the problem? As you drew it, there isn't enough to solve.

Answer 4

wait let me draw it again.

Answer 5

omg, you know what, i got the wrong one "_"

Answer 6

okay so i need to find the value of the variable

Answer 7

That's better...

Answer 8

since all of those are consecutive interior angles, they're 180 correct?

Answer 9

I have to admit, it's been awhile.

I don't recall "consecutive interior angles," so I'm not sure about that.

I am reasonably sure that the sum of the exterior angles for a 4-sided figure will equal 360 degrees (in fact, that's true regardless of number of sides). And each pair of interior and exterior angles sums to 180. There is enough to set up some equations.

However, if you know for sure about consecutive interior angles, that might be easier

Answer 10

Since consecutive interior angles are supplementary, then I guess they are equal to 180 degrees.

Answer 11

if they are supplementary, you are right, they add to 180. I just don't remember that rule/theorem... but I am not at all doubting you, I just don't remember.

Answer 12

But, I'm still confused to what I should do:
2x + 96 = 180?
3y + 44 + 94 = 180?

Answer 13

ok, I just googled "consecutive interior angles"... they only add to 180 if the lines crossing are parallel

Answer 14

O.O okay.. this is gonna be harder than i thought '-'
