Question

If m(arc BY)= 44, enter the
mZY AC.

(The figure is not drawn to scale.)

Answer 1

Answer:
`68^(\circ)`

Explanation:

Assuming AC is a tangent, this means
`m\angle BAC=90^(\circ)`.

Since arc BY measures 44 degrees, by the inscribed angle theorem,
`m\angle BAY=22^(\circ)`.

This means
`m\angle YAC=90^(\circ)-22^(\circ)=68^(\circ)`
