Question

What is the measurement of arc AC?Please choose either A, B, C, or D.

Answer 1

The inscribed angle is 42 degree.

To determine the measure arc AC,

Use the formula

`m\angle ABC=(1)/(2)m\hat{AC}`
`m\hat{AC}=2*42^(\circ)=84^(\circ)`

Hence the measurement of arc AC is 84 degree .

Hence the correct option is d.
