A quadrilateral has two angles that measure 255° and 80°. The other two angles are in a ratio of 2:3. What are the measures of those two angles?

42° and 63°

Explanation:

The sum of angles in a quadrilateral is 360°,

  So,

 Given angles;

       255° and 80°

The other two angles;

       360  = 255 + other two angles  

       other two angles  = 360 -255 = 105°

The ratio of the remaining two = 2:3

  Angle 1 = x 105  = 42°

   Angle 2 = x 105  = 63°
