Which of the following equations has both -2 and 2 as possible values of b?

3. 8,935,200 minutes

4. 227,040 feet

1.44 centimeters is the correct answer

we know that

1) the inscribed angle measures half of the arc it comprises.

so

m∠dgf= > expression

2) the opposite angles in an inscribed quadrilateral are supplementary angles

so

m∠dgf=

m∠dgf=°

substitute in the expression to find the value of arc ef

therefore

the answer is

the measure of the arc ef is
