Question

Answer 1

`EBF` Is the vertex angle that is outside of the circle....

We know of the arc of `DA` and `EF` so we would use this equation...

\(\huge{\frac{1}{2} \times (\angle 1 - \angle 2)=x}\)

So we identify which angle is 1 and 2....Now angle 1 is the angle that is the largest which would be the arc that is the farthest so that would be `EF`....

\(\huge{\frac{1}{2} \times ( 100-35)=x}\)

Simplify. ;)
