Question

I FAN AND MEDAL BUT PLEASE HELP ME!



Which relationship is always correct for the angles x, y, and z of triangle ABC?

A triangle ABC has angle ABC labeled as y, angle ACB labeled as z, and the exterior angle at A labeled as x.
x + z = y
y + z = x
x + y + z = 180 degrees
x + y + z = 90 degrees

Answer 1

I would say B. y+z=x

Answer 2

you shure?

Answer 3

well thats what I would pick if i had that test

Answer 4

after you do the test send me a message and tell which it was k?

Answer 5

k meanwhile can u help me? on anuther?

Answer 13

sure i guess

Answer 14

I can help you figure it out, but I will not just give you the answer flat out.

Answer 15

OK

so let's call the angle at A "a"

what do oyu know about x+y+a (the sum of the internal angles of a triangle)??

Answer 16

yes they all add up to 180 right?

Answer 17

good yes

now x and a are angles on a straight line so what is x+a?

Answer 18

um 180 degrees?

Answer 19

good

so you have:


so what is true about the 2 terms in the ring?
