Angles S, T and SUT must add to 180 degrees because they're the interior angles of a triangle. The angles at point U (SUT and FUT) are supplementary, so they also add to 180 degrees. This means [latex]SUT=180-(18x+2)=178-18x[/latex]. So, [latex](2x+3)+95+(178-18x)=180[/latex] [latex]-16x+276=180[/latex] [latex]96=16x[/latex] [latex]x=6[/latex]
