You can put this solution on YOUR website!
You can find the x and y components
\n" ); document.write( "of each vector, then add x's, then
\n" ); document.write( "add y's. The vector sum can then be found
\n" ); document.write( "------------------------------------------
\n" ); document.write( "\"+A%5Bx%5D+=+-A%2Acos%284%29+\"
\n" ); document.write( "\"+A%5By%5D+=+-A%2Asin%284%29+\"
\n" ); document.write( "------------------------
\n" ); document.write( "Note that 184 degrees is in the 3rd
\n" ); document.write( "quadrant where both sin and cos are negative
\n" ); document.write( "\"+184+-+180+=+4+\" is the angle the
\n" ); document.write( "vector makes with the x-axis
\n" ); document.write( "-----------------------------
\n" ); document.write( "\"+B%5Bx%5D+=+B%2Acos%2812%29+\"
\n" ); document.write( "\"+B%5By%5D+=+-B%2Asin%2812%29+\"
\n" ); document.write( "-------------------------
\n" ); document.write( "Vector B is in the 4th quadrant where
\n" ); document.write( "the cos is positive and sin is negative
\n" ); document.write( "\"+360+-+348+=+12+\" is the angle B
\n" ); document.write( "makes with the x-axis
\n" ); document.write( "----------------------
\n" ); document.write( "\"+A%5Bx%5D+%2B+B%5Bx%5D+=+-A%2Acos%284%29+%2B+B%2Acos%2812%29+\"
\n" ); document.write( "\"+A%5Bx%5D+%2B+B%5Bx%5D+=+-352%2A.9976+%2B+283%2A.9781+\"
\n" ); document.write( "\"+A%5Bx%5D+%2B+B%5Bx%5D+=+-351.1552+%2B+276.8023+\"
\n" ); document.write( "\"+A%5Bx%5D+%2B+B%5Bx%5D+=+-74.3529+\"
\n" ); document.write( "------------------------------
\n" ); document.write( "\"+A%5By%5D+%2B+B%5By%5D+=+-A%2Asin%284%29+-+B%2Asin%2812%29+\"
\n" ); document.write( "\"+A%5By%5D+%2B+B%5By%5D+=+-352%2A.0698+-+283%2A.2079+\"
\n" ); document.write( "\"+A%5By%5D+%2B+B%5By%5D+=+-24.5696+-+58.8357+\"
\n" ); document.write( "\"+A%5By%5D+%2B+B%5By%5D+=+-83.4053+\"
\n" ); document.write( "------------------------------
\n" ); document.write( "These magnitudes both being negative means
\n" ); document.write( "the resultant vector is in the 3rd quadrant
\n" ); document.write( "Call the resultant vector \"+C+\"
\n" ); document.write( "\"+C%5E2+=+%28+-74.3529+%29%5E2+%2B+%28+-83.4053+%29%5E2+\"
\n" ); document.write( "\"+C%5E2+=+5528.3537+%2B+6956.4441+\"
\n" ); document.write( "\"+C%5E2+=+12484.7978+\"
\n" ); document.write( "\"+abs%28+C+%29+=+111.7354+\"
\n" ); document.write( "This is the magnitude of the resultant vector, \"+C+\"
\n" ); document.write( "-----------------------------
\n" ); document.write( "The angle, \"a\" with the x-axis is:
\n" ); document.write( "\"+cos%28a%29+=+74.3529+%2F+83.4053+\"
\n" ); document.write( "\"+cos%28a%29+=+.8915+\"
\n" ); document.write( "\"+a+=+26.9377+\"
\n" ); document.write( "This angle is in the 3rd quadrant, so I have
\n" ); document.write( "to add \"+180+\" degrees
\n" ); document.write( "\"+a+%2B+180+=+26.9377+%2B+180+\"
\n" ); document.write( "\"+a+%2B+180+=+206.9377+\"
\n" ); document.write( "-----------------------------
\n" ); document.write( "So, the answer is:
\n" ); document.write( "111.7354 angle 206.9377
\n" ); document.write( "Unless I made an error ( very possible )
\n" ); document.write( "-----------------------------------------
\n" ); document.write( "This method always works. you might be asked
\n" ); document.write( "to do it a different way, but the result
\n" ); document.write( "should be the same
\n" ); document.write( "hope this helps
\n" ); document.write( "
\n" ); document.write( "
