the measure of the angles in a triangle are 100, 5x+8 and 3x. solve for x and
\n" ); document.write( " find the measures of the two angles.
\n" ); document.write( ":
\n" ); document.write( "100 + (5x+8) + 3x = 180
\n" ); document.write( "5x + 3x + 8 = 180 - 100
\n" ); document.write( "8x = 80 - 8
\n" ); document.write( "8x = 72
\n" ); document.write( "x = 72/8
\n" ); document.write( "x = 9:
\n" ); document.write( "2nd angle: 5(9)+8 = 53 degrees
