a) what is the sum of the angles of the triangles in terms of x? 63.3
b) write an equation linking your answer to a) 180 = 63.3 *(3*3*2+20)
this is what i did to try'n solve the equation but i couldn't make it work XD

The angles of the triangles look something like this
3x+20
2x
3x
Thus looking like an equilateral triangle with all size equaling the same.

Your post is not clear. How many triangles are there? Please provide all of the given information, including the diagram.
 
the triangle is just one and it has the sides given above it might be a little wild out but those are the sides to it.
I've already solved for x so that part is clear, everything else like part b is the part i wanted to answer which i got wrong.
 
3x+20 + 2x + 3x = 180
Solve for x.
But this person just posted that they're already solved for x.

They also posted (earlier) that the sum of the angles in terms of x is 63.3

This thread still makes little sense, to me. I requested the complete exercise statement and diagram, but Illvoices is seemingly not interested in following our guidelines. :(
