Question

if TRAP is an isosceles trapezoid, what is the value of x?

Answer 1

6 is not correct. I tried doing 4x+12=2x and apparently thats not the correct equation.

Answer 2

I think you need to multiply those terms by 2.
Because you have both sides are the same and the other two are the same.
And the inner angle of a trapezoid is 360
So it would be like this:
2(4x+12)+2(2x)=360

Answer 3

And you get
x=?

Answer 4

Okay. So it will always equal 360?

Answer 5

If it has 4 sides.
The formula of a regular shape would be like this if you want to know the sum of theinner angles:
(n-2)*180, where n is the number of sides

Answer 6

So a triangle would have:
(3-2)*180=180

Answer 7

Ok, I got 28. I'll see if that works. And thanks for the info! That makes more sense.

Answer 8

Ohh, it doesn't matter if it is regular or not. It is just for a polynomial I remember now XD.
