I would say B. y+z=x
well thats what I would pick if i had that test
after you do the test send me a message and tell which it was k?
k meanwhile can u help me? on anuther?
idk, i guess he knows.
he tried at least.
What is this for? I don't feel comfortable helping if it is for something like a test or a quiz...
lol no its not, its just like a review of what i know already but that question really got me.
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)
sure i guess
I can help you figure it out, but I will not just give you the answer flat out.
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)??
yes they all add up to 180 right?
good yes now x and a are angles on a straight line so what is x+a?
um 180 degrees?
good so you have: |dw:1444231866005:dw| so what is true about the 2 terms in the ring?
they both add up to 180
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'?
uh... it means that um.. they add up to something that when its added to A its 180?????? idk
lol i am just dumb at math :(
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?
OH DAMN I GET IT
y + z =x
so x is 2 times bigger than z and y
ok and now what?
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...
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...
i meant z is half of x
oh lol thank you ,,,, do you think you can help me wif another?
