Question

The exterior angles of a triangle measure x°, (2x)°, and (3x)°. What is the value of x?
	A.	60
	B.	72
	C.	30
	D.	45

sum of the interior angles is 180 se was can put 
$$x+2x+3x=180$$ and solve for $x$
$$6x=180$$ one more step

anonymous · Answer

So to find that answer, do I find a number that plugs into x that will get it to equal 180?

anonymous · Answer

you could do that but it would be quicker to divide 180 by 6 instead of guessing and checking

anonymous · Answer

i mean yes, that is what you want, but to find it, divide $180\div 6$

anonymous · Answer

So then my answer would be, C. 30!

anonymous · Answer

yes that does it!

anonymous · Answer

Thank you very much for taking the time to help me! (: I appreciate it! <3

anonymous · Answer

i think it would be A

anonymous · Answer

yes i could learn to read it says EXTERIOR ANGLES doesn't it
damn

anonymous · Answer

and they add up to 360 so we must solve 
$$x+2x+3x=360$$
$$6x=360$$
$$x=360\div 6=60$$ sorry about that

anonymous · Answer

addition of supplement of exterior angles is 180
