Question

Determine the measure of arc BD.

47.7°


mBD =


degrees

Answer 1

From CIRCLE THEOREM: The angle at the centre of a circle is twice the angle at its circumference.

The above circle with O as its centre subtends an arc BD

The angle at the circumference is 47.7degrees;

`\begin{gathered} \angle Arc\text{ BD=2}*47.7^o \\ \angle Arc\text{ BD=9}5.4^o \end{gathered}`

The measure of Arc BD is 95.4degrees
