<PRE><B>Question 943167</B>
Sum of supplementary angles=180 degrees
Let A=angle; Let A+110.6=supplementary
A+A+110.6=180 degrees Subtract 110.6 from each side
2A+110.6-110.6=180-110.6
2A=69.4 divide each side by 2
{{{2A/2=69.4/2}}}
A=34.7 degrees ANSWER Angle is 34.7 degrees
34.7+110.6=145.3 degrees ANSWER Supplementary angle is 145.3 degrees
CHECK
34.7 degrees+145.3 degrees=180 degrees
180 degrees=180 degrees</PRE>
