i have an isosceles triangle. One angle has 3x and the other angle has (x+50).
\n" ); document.write( "How to find the third angle.
\n" ); document.write( "-------------------------------------------
\n" ); document.write( "That depends on which of the two you listed is one of the equal angles.
\n" ); document.write( "---
\n" ); document.write( "If 3x is paired with another 3x you get:
\n" ); document.write( "3x + 3x + x+50 = 180
\n" ); document.write( "7x = 130
\n" ); document.write( "x = 130/7
\n" ); document.write( "---
\n" ); document.write( "3x = 390/7
\n" ); document.write( "x+50 = (130/7) + (350/7) = 480/7
\n" ); document.write( "=============================================
\n" ); document.write( "If (x+50) is paired with another (x+50) you get:
\n" ); document.write( "2(x+50) + 3x = 180
\n" ); document.write( "5x = 80
\n" ); document.write( "x = 16 degrees
\n" ); document.write( "3x = 48
\n" ); document.write( "x+50 = 66 degrees.
\n" ); document.write( "---------------------------------------------
\n" ); document.write( "Comment:
\n" ); document.write( "Judging from those answer I would guess the x+50
\n" ); document.write( "is one of the two equal angles.
\n" ); document.write( "======================================
