what is the measures of each of the angles? The second angle in a triangle is one and a half times the measure of the first. The third is 15 degrees more than half the first angle. can you also show how to figure this?:
\n" ); document.write( ":
\n" ); document.write( "let x = \"the first angle
\n" ); document.write( ":
\n" ); document.write( "Write an equation for each phrase.
\n" ); document.write( ":
\n" ); document.write( "\"The second angle in a triangle is one and a half times the measure of the first.\"
\n" ); document.write( "1.5x = the 2nd angle
\n" ); document.write( ":
\n" ); document.write( "\" The third is 15 degrees more than half the first angle.\"
\n" ); document.write( ".5x + 15 = the 3rd angle
\n" ); document.write( ":
\n" ); document.write( "We know the 3 angles = 180, therefore
\n" ); document.write( "x + 1.5x + (.5x+15) = 180
\n" ); document.write( "x + 1.5x + .5x = 180 - 15
\n" ); document.write( "3x = 165
\n" ); document.write( "x = \"165%2F3\"
\n" ); document.write( "x = 55 degrees is the 1st angle
\n" ); document.write( "then
\n" ); document.write( "1.5(55) = 82.5 degrees is the 2nd angle
\n" ); document.write( "and
\n" ); document.write( ".5(55) + 15 = 42.5 degrees is the 3rd angle
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "See if this checks out
\n" ); document.write( "55 + 82.5 + 42.5 = 180, it does\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
\n" );
