Question

Find the indicated measure. Lines that appear to be tangent aretangent.

Answer 1

`m\angle A=3\text{ (angle in alternate segment)}`
`\begin{gathered} 216^0\text{ is the angle subtended by the arc at the centre of the circle} \\ T\text{hus,} \\ 216=2\text{ }* m\angle3 \\ m\angle3=(216)/(2) \\ m\angle3=108^0 \end{gathered}`

Hence, the measure of angle 3 is 108 degrees.
