Question 212955
Let the angle be A, then its supplement is 180-A and its complement is 90-A.
{{{highlight_green(180-A = 3(90-A)+2)}}} Simplify and solve for A.
{{{180-A = 270-3A+2}}} Add 3A to both sides.
{{{180+2A = 272}}} Subtract 180 from both sides.
{{{2A = 92}}} Divide both sides by 2.
{{{highlight(A = 46)}}}degrees.
