In my homework for tonight there is a problem that says:

Ramping Up a civil engineer is planning a highway overpass as shown in the figure. Find the degree measure of the angle marked w.

I'm not sure how to set this problem up. I thought maybe it would involve
w+2w+2w+40=180 but I'm not sure.

Any help would be greatly appreciated. Thank you.

look at the linear pair of angles to the right ... their sum is 180 degrees.

2w + (2w+40) = 180

solve for w

Ah... now it makes sense. Thank you very much.
