Question

An angel is 5 times its supplement find the measure of bith angels

Answer 1

Now, supplementary angles sum up to 180°.

so hmmm say one has a measure of a°, and her sibling is 5 times larger, or 5 times that much, or 5a°, we know that both will sum up to 180°, thus

$\bf a+5a=180\implies 6a=180\implies a=\cfrac{180}{6}\implies a=30$

so, the smaller is that much, and her sibling is 5a, and you know how much that is, unless you mean angels, and  hmmmm both have wings and feathers and are wearing a gown, but doubt that's the case.
