Question

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?

Answer 1

Thanks Mertsj!

Answer 2

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

Answer 3

yup. I'm not that dumb lol

Answer 4

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

Answer 5

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

Answer 6

thanks!

Answer 7

Yes. x = 30 and 2x = ? and 3x= ?

Answer 8

wait is that right?

Answer 9

2x=60

Answer 10

3x=90

Answer 11

Do those 3 add up to 180?

Answer 12

30 +60+90 = 180!

Answer 13

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

Answer 14

I'm not in a grade.
