It would be nice if you were to tell us what kind of figure you had in mind.
\n" ); document.write( "I have to deduce that it is a quadrilateral since you mention only four angles.
\n" ); document.write( "Let's use the following facts:
\n" ); document.write( "The sum of the four angles in any quadrilateral is 360 degrees.
\n" ); document.write( "If two angles are complimentary, then their sum is 90 degrees.
\n" ); document.write( "So, Angle 2 plus angle 3 = 90 degrees.
\n" ); document.write( "Then the sum of angles 1 and 4 is 360-90 = 270 degrees, and angle 4 is 270-130 = 140 degrees.
\n" ); document.write( " \n" ); document.write( "
