\n" ); document.write( "Adjacent angles of a trapezoid are supplementary.

\n" ); document.write( "Since angles A and C are opposite angles and are supplementary, we know angles B and D have the same measures as angles A and C.

\n" ); document.write( "But there is not enough information to know which is which....

\n" ); document.write( "ANSWER: In either order, the measures of angles B and D are 59 and 121 degrees.
