Help @ganeshie8 @Isaiah.Feynman @ikram002p

Answer 2

HELP ANYONE! I just need someone to walk me through it!

Answer 3

I know it isn't obtuse

Answer 4

Things would be so much simpler if you only knew what the bloody hell x is equal to, yes? ^_^

Answer 5

Yes, but I don't

Answer 6

You don't, well naturally. (no offense meant, apologies if you took any, I only meant that if you did, you wouldn't post this question ^_^)


Anyway, you don't know, but you will know, with a little magic.

Incidentally, when you add up all the angles inside a triangle, it's always equal to a certain number of degrees, do you know which?

Answer 7

Yes, 180 degrees

Answer 8

Brilliant.
So add up all those sides, and make them equal to 180.

Answer 9

x doesn't equal 20

Answer 10

... how do you get 20? :/

Answer 11

x=40?

Answer 12

I was plugging in numbers

Answer 13

Don't guess LOL
What are the three sides?

Answer 14

in terms of x is fine.

Answer 15

x, x+20, 2x

Answer 16

Add them up.

Answer 17

4x+20+180

Answer 18

whoa there, where did 180 come from? LOL

Answer 19

Just add up the three sides.

Answer 20

Oops... =180

Answer 21

Oh okay, typo then.
Good.
4x + 20 = 180

Solve for x...

Answer 22

160 is left over

Answer 23

mhmm ^_^

Answer 24

160 divided by 4= 40

Answer 25

So x is 40 right?
And no more guessing... this is more efficient, yes? XD

x is 40, so what are the other three angles?

Answer 26

40, 60, 80

Answer 27

Okay, from these, you can get your answer :D

Answer 28

40+60+80= 180

Answer 29

Yeah, that, but what's the answer to the original question?
What kind of triangle is it?

Answer 30

So, acute right?

Answer 31

That is correct :)

Good job, <whatever your name is>

Answer 32

See, you CAN do it.

All you needed was a little magic.
