In an isosceles triangle, the 2 base angles are equal, and the third is the vertex angle.\r
\n" ); document.write( "\n" ); document.write( "Also, sum of the 3 angles is 180 deg.\r
\n" ); document.write( "\n" ); document.write( "If the base angle is x, the other base angle is also x\r
\n" ); document.write( "\n" ); document.write( " $\"x+%2B+x+%2B+30+=+180\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"2x+=+150\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"highlight%28x+=+75%29\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"highlight%28Measure+of+base+angle+=+75+degrees%29\"$ \r
\n" ); document.write( "\n" ); document.write( ":) \n" ); document.write( "
