Mathematics

Find the supplementary angle of $$87^{\circ}$$.


SOLUTION
Let $$x$$ be the supplementary angle of $$87°$$.
As we know that supplementary angles equal $$180$$ degrees.
Therefore,
$$x + 87° = 180°$$
$$\Rightarrow x = 180° - 87° = 93°$$
Hence the supplementary angle of $$87°$$ is $$93°$$.
