Answer:
50 degs
140 degs
145 degs
Explanation:
Complementary angles are two degree angles that add up to 90 degrees.
You can take what's given of 40 degs and do 90 - 40 to get the missing angle.
Supplementary angles add to 180 degs so 180 - 40 = 14.

--> They also are straight lines pretty much since a linear/straight line is 180 degrees.
So 180 - 35 = 145
