Question

Find the measure of an angle such that the measure of its supplement is 54 degrees more than twice that of its supplement.

Answer 1

Let's call the angle A.

Supplement means the angle that, when added to the first, makes the whole thing equal to 180 degrees.

Let's call A's supplement B.

A+B=180.

From your directions, B=2B+54.
-B=54.
B=-54. Angles can't be negative, so this is not possible (unless I read wrong).

Answer 2

the answer needs to be 42
