An angle measures 143.4° more than the measure of a supplementary angle. what is the measure of each angle?

This is a typical story problem that needs to be translated from written words to a workable equation.  "An angle measures" looks like "A =" in equation form.  "...the measure of a supplementary angle" looks like "(180 - A)" and "143.4 more" means you're adding 143.4 to the (180 - A).  So in the end the equation is this: A = (180 - A) + 143.4.  This simplifies to A = 323.4 - A, and adding A to both sides gives us 2A = 323.4 and A = 161.7.  Now check yourself by filling in 161.7 for every A in your original equation and make sure it comes out right and that the right side does in fact equal the left side.  (It does, just check it anyway!)

The answer is b) 32 your welcome
