In triangle JKL,the measure of angle j is 30 degrees less than the measure of angle K and measure angle L=80. find measure angle K.\r
\n" ); document.write( "\n" ); document.write( " Let angle K be = x\r
\n" ); document.write( "\n" ); document.write( " then angle J will be = x-30 degrees\r
\n" ); document.write( "\n" ); document.write( " angle L = 80 degrees
\n" ); document.write( "
\n" ); document.write( " sum of the three angles in a triangle = 180 degrees\r
\n" ); document.write( "\n" ); document.write( " i.e , K+L+J = 180
\n" ); document.write( "
\n" ); document.write( " x+80+x-30 = 180\r
\n" ); document.write( "\n" ); document.write( " 2x = 180-80+30
\n" ); document.write( " = 130\r
\n" ); document.write( "\n" ); document.write( " x= 130/2 = 65 degrees\r
\n" ); document.write( "\n" ); document.write( " hence angles of the triangle are , K = 65 deg, L = 80 deg & J = 35 deg.\r
\n" ); document.write( "
