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

I would say B. y+z=x

well thats what I would pick if i had that test

- SupDaSup

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

- anonymous

k meanwhile can u help me? on anuther?

- SupDaSup

Sure

- MrNood

@pandaluvs
do you think that that is a sufficient reason to choose the answer - just cos @SupDaSup "thinks so"

- anonymous

idk, i guess he knows.

- anonymous

he tried at least.

- anonymous

What is this for? I don't feel comfortable helping if it is for something like a test or a quiz...

- anonymous

lol no its not, its just like a review of what i know already but that question really got me.

- MrNood

do you want to see how to do it ? or are you gonna just trust someone you don't know?
(MANY answers given here are just plain WRONG)

- anonymous

sure i guess

- anonymous

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

- MrNood

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)??

- anonymous

yes they all add up to 180 right?

- MrNood

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

- anonymous

um 180 degrees?

- MrNood

good
so you have:
|dw:1444231866005:dw|
so what is true about the 2 terms in the ring?

- anonymous

they both add up to 180

- MrNood

SORRY - I made a mistake a few post back
it is y+z+a = 180 (i WROTE X+Y+A) but it doesn't change the method.
Your answer is not correct above:
look at the 2 equation
something + a = 180
something ELSE +a = 180
so what is true about the 2 'somethings'?

- anonymous

uh... it means that um.. they add up to something that when its added to A its 180?????? idk

- anonymous

lol i am just dumb at math :(

- MrNood

OK since they both add up to 180 you coiuld write
y+z+a = x+a
OK?
what happens if oyu then subtract a from each side?

- anonymous

OH DAMN I GET IT

- anonymous

y + z =x

- anonymous

so x is 2 times bigger than z and y

- anonymous

ok and now what?

- MrNood

ok - well done.
NOW - you were probably 'DUMB' at everthing else until you LEARNT it
Maths is not inherently hard - it is just ans excuse to say you ar edmb.
When learnt like anything else it gets easier - and in fact is easier to get high marks because it is RIGHT or wrong - no-one can argue with a correct method...

- MrNood

WHOOOOA!
x is NOT 2 times bigger
all you can see is the y+z=x
that is the answer - it is one of the optins...

- anonymous

i meant z is half of x

- anonymous

oh lol thank you ,,,, do you think you can help me wif another?

- anonymous

Learnt is not a word. The correct way to say that is "...before you learned it." @MrNood
