Find the angles in a triangle if the measures of the angles are
a.) x, 2x, and 3x
b.) x-10,x, and x+10
I'm in grade nine. Exam on monday! I have no idea what this question is talking about, oh yea, is there a way to change my username? I made it a year ago and I want to change it to TrueDirectioner or VasHappening?

Do you know that when you add the three angles of a triangle you always get 180?

So they said the three angles of the triangle are x, 2x and 3x. So you should write and solve the equation that says the sum of those 3 is 180

x+2x+3x=180
6x=180
*180 divided by 6*
x= 30

Do those 3 add up to 180?

30 +60+90 = 180!

So now you have found the 3 angles of that triangle. And the b example is similar.
