Question

What is the supplement of a 70 degree angle?

Answer 1

`110˚`

Explanation:

Supplementary angles have a sum of `180˚`.

Thus, if `angle1` and `angle2` are supplementary,

`mangle1+mangle2=180`

We know that `mangle1=70` and we want to find `mangle2`.

`70+mangle2=180`

Subtract `70` from both sides.

`mangle2=110`

Thus, a `70˚` angle and a `110˚` angle are supplements of one another.
