in order to find out which angle is the longest, you need to figure out each triangle's measurement. the inner and outer angles at W add up to 180 since they're on a straight line. therefore, the inner angle W is 180 - 125 angles R, W, and E make up a triangle, so angle E = 180 - angle R - angle W once you have all three angles, the longest side is *across* from the longest angle.

Thank you Vocaloid!!!

mine:

it would be angle e because if the exterior angle of w is 125 then it wouldn't be that big of an angle. Angle r is only 50 degrees, therefore that leaves angle e to be the biggest
