Given a triangle with angle measures a, b and c degrees,
then a+b+c = 180°.
This is always true.
So:
45°+50°+x°=180°
95°+x°=180°
x°=180°-95°=85°
So the measure of the missing angle is 85°.
Thus x>50°>45°
Another important theorem is that the angle measures and the lengths of the sides opposite these angles are directly proportional,
that is, the larger side is opposite the larger angle.
Answer:
(side length opposite) x> (side length opposite) 50°> (side length opposite) 45°
