Can you find two angles that are identical and are in terms of , equate them to get an equation in and then solve for . Then you know two of the angles in the triangle and can say that the two angles + t = 180. Then solve for .

I done 3w+40=180 then solved that and got 46.6 is that correct so far?

I'm not sure how you got that... where did it come from? This may be useful:

I added the 2w in the triangle with the w+40 on the line and since the w+40 is on a straight line it would add up to 180 that's how I got 3w+40=180

How did you get that in the triangle?

From there I hope you can see it

the "2w" in your triangle should be 72 from the alternate angles theorem, look a few posts up for the picture I posted.

Could you tell me how you would do this please?
