Re: finding x on a triangle.

Hi;

I am not sure what you want. Always copy the question exactly. Let's try this:

The sum of the angles of a triangle equal 180 degrees.

180 - 57 - 64 = 59

5x + 4 = 59

5x = 55

x = 11.


In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.
