The two angles are complementary angles. By definition, they add to 90 degrees. \r

\n" ); document.write( "\n" ); document.write( "(measure of angle 1) + (measure of angle 2) = 90
\n" ); document.write( "(5y+1) + (3y-7) = 90
\n" ); document.write( "5y+1 + 3y-7 = 90
\n" ); document.write( "(5y+3y) + (1-7) = 90
\n" ); document.write( "8y - 6 = 90
\n" ); document.write( "8y - 6+6 = 90+6
\n" ); document.write( "8y = 96
\n" ); document.write( "8y/8 = 96/8
