2. What did you use to find the measure of angle A? (1 point)
A. 60 + x + A = 180
B. 180 – 150 = A
C. Interior angles are equal
D. Vertical angles are equal

Have to copy and paste the whole link.

Answer 1

i don't know...I can upload it somewhere else.

Answer 2

Thanks.

Answer 3

A should equal 60, intersection and all that

Answer 4

So your saying it equals 60 and number 2 is ???

Answer 5

I'd go with the interior angle answer,...if I remember correctly, it means the same thing as saying " opposit angles are equal"

Answer 6

that;s not right saw my error

Answer 7

vertical angles are equal

Answer 8

That's true^

Answer 9

meaning that A= 60 because it is an angle of intersecting lines, aka A=60 because they are vertical angles

Answer 10

Ohh..so did you just solve those equations then subtracted it?? I'm trying to understand I'm just not good with Geometry.

Answer 11

What I did was make an inference based off of vertical angle theorem. If there are two lines that intersect, then they will create four angles. Each angle has an opposing angle, vertical from its perspective. The two opposite or vertical angles are equal

Answer 12

Jazy seems to have a more current handle on geometry than me, so correct me if any of that is innacurate

Answer 13

Vertical angles are equal. ex:

Answer 14

Nope. You're completely right @karama (:

Answer 15

^^^ I understand that with the pic..thanks guys. :))

Answer 16

you're welcome...let us know if you have any other questions! :)

Answer 17

Sure thing.

Answer 18

Can I have help with finding the degree of x?

and Which of the following can you use to find the degree measure of angle x?
180 – (60 + A) = x
150 – 60 = x
x = 60 + A
x = 150 – 50
180 – 90 = x
These are my last questions that I need help with.

Answer 19

The same triangle?

Answer 20

Yes.

Answer 21

let's see, it might be 90...because y=30, since 180-150=30...then 60+30=90...triangles must have angles that sum to 180...180-90=90

Answer 22

ohhh..Okay I understand that.

Answer 23

\[180=\alpha+\beta +\gamma\]
each symbol represents an interior (meaning inside of) angle of a triangle

Answer 24

as well, in case you need any reference for how I got the value of Y

Answer 25

Yeah.. I'm understanding it..Thanks again.
