Question

In the circle below, if < BAC = 36 °, find the arc measure of arc BC.

Answer 1

Given:

`\angle BAC=36^(\circ)`

Find-:

The arc of BC.

Explanation-:

The arc of BC is:

According to property, the angle is:

`\angle BOC=2\angle BAC`

So, the arc of BC is:

`=2\angle BAC`
`\begin{gathered} =2\angle BAC \\ \\ =2*36 \\ \\ =72^(\circ) \end{gathered}`

The arc of BC is 72°.
