You can put this solution on YOUR website!
it's very difficult to explain because the diagram could have been more helpful.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "what i get is:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "yes, the slata going in the same direction are parallel to each other.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "angle A is a vertical angle with a 50 degree angle, therefore it is also 50 degrees.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "angle B is part of parallelogram PQRS (my nomenclature) and is adjacent angle to angle PQR which is 80 degrees because it is a vertical angle with the 80 degree angle shown.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "since angle PQR is adjacent to angle PQR, then it is supplementary to it and is therefore 100 degrees.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "angle PQR is the angle B that was given in the original diagram.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "angle PSR is part of parallelogram PQRS and is opposite the 80 degree angle PQR and is therefore 80 degrees as well because opposite angles of a parallelogram are congruent.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "angle C is vertical to angle PSR and is therefore also 80 degrees.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "my answers:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "angle A is 50 degrees.
\n" ); document.write( "angle B is 100 degrees.
\n" ); document.write( "angle C is 80 degrees.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "here's my diagram of the diagram you were given.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"$$$\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "in this diagram:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "lines x, y, and z are all horitonztal lines and therefore parallel to each other.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "lines DG and EF are parallel to each other since they are on oppositie sides of the slat.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "lines HK and IJ are paralell to each other since they are on opposite sides of the same slat. \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "PQRS is a parallelogram because opposite sides of it are parallel to each other.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "angle PQR is 80 degrees because it is vertical angle to the 80 degree angle shown.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "angle PSR is also 80 degrees because opposite angles of a parallelogram are congruent.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "angle SPQ is 100 degrees because it is an adjacent angle to the 80 degree angles of the parallelogram and adjacent angles of a parallelogram are supplementary.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "angle SRQ is also 100 degrees because it is opposite to angle SPQ and opposite angles of a parallelogram are congruent.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "angle C is 80 degrees because it is a vertical angle to angle PSR which is 80 degrees.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "that should be it.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "there are other relationships formed from the diagram but they are unnecessary to provide you with the answer you seek.\r
