Question

what is the supplement 180-x = _____

Answer 1

Explanation:

We wish to find the supplement of 180 - x.

We know that an angle is the supplement of another if they add to have a sum of 180°.

So here, we need to find a value for which 180 - x shall become 180, and it is only logical that the answer for this is x.

$\mathsf{x+(180-x)=180}$

∴ $\mathsf{180=180}$

Hence, the supplement is x.

Answer: x
