Question

In the diagram m < AFB = 78, Which angle is supplementary to

Answer 1

The angle supplementary to
`$\angle A F B$` is
`$\angle A E D$`.

Supplementary angles add up to
`$180^(\circ)$`, so
`$\angle A E D+\angle A F B=180^(\circ)$`.

Since
`$\angle A F B=78^(\circ)$`, we have
`$\angle A E D+78^(\circ)=180^(\circ)$`.

Solving for
`$\angle A E D$`, we get
`$\angle A E D=180^(\circ)-78^(\circ)=102^(\circ)&`.

Therefore,
`$\angle A E D$` is supplementary to
`$\angle A F B$`.

Answer 2

BFD

Explanation:

Supplementary angles add to 180, or will form a straight line.

< AFB and angle BFD will form a straight line so they are supplementary.
