Question

Each row in the table below shows one possible set of angle measurements for this drawing.

Answer 1

First let;s fill the second row

It is given that

`\begin{gathered} \angle DFE=36 \\ \angle AFE=180-36=144 \end{gathered}`
`\angle AFB=36\text{ (VERTICALLY O}\P OSITE\text{ TO }\angle DFE)`
`\angle BFC=90-36=54`

Now let us fill the third row :-

It is given that

`\angle AFE=140`

So

`\angle DFE=180-140=40\text{ (LINEAR PAIR)}`
`\angle AFB=\angle DFE=40\text{ (vertically opposite angles)}`
`\angle BFC=90-40=50\text{ }`
