THE SECOND ANGLE OF A TRIANGLE IS TWO TIMES AS LARGE AS THE FIRST.THE THIRD ANGLE IS 10 DEGREES MORE THAN THE SECOND ANGLE. FIND THE MEASURE OF THE FIRST ANGLE.\r
\n" ); document.write( "\n" ); document.write( "Let the first angle = A.
\n" ); document.write( "Then, the second angle = 2A.
\n" ); document.write( "The third angle = 2A+10.
\n" ); document.write( "The 3 angles add up to 180 (for all triangles.)\r
\n" ); document.write( "\n" ); document.write( "So, $\"A%2B2A%2B%282A%2B10%29+=+180\"$ .
\n" ); document.write( "Or, $\"5A%2B10+=+180\"$ .
\n" ); document.write( "Or, $\"5A=170\"$ .
\n" ); document.write( "Or, $\"A=170%2F5+=+34+degrees\"$ .\r
\n" ); document.write( "\n" ); document.write( "Verification:\r
\n" ); document.write( "\n" ); document.write( "First angle = 34.
\n" ); document.write( "Second angle = 2*first angle = 68.
\n" ); document.write( "Third angle = second angle + 10 = 78.\r
\n" ); document.write( "\n" ); document.write( "The three angles add up to 34+68+78 = 180. \n" ); document.write( "
