An airplane can fly at a speed, that allows it to fly 50 yards in 3⁄2 of a second. how long will it take an airplane at the same speed to fly 20 yards? write your answer as a fraction of a second.

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
