Question

If the measure of `∠K` is 29 degrees and it is supplementary with `∠J`, what is the measure of `∠J`?

Answer 1

`J=151°`

Explanation:

Two angles are supplementary if they sum up to `180°`.

So, an angle `J` is supplementary to `K` if `J+K=180`. Since we know that `K=29°`, we can easily find `J`:

`J+K=180° iff J+29°=180° iff J=180°-29°=151°`
