At time x=0, water begins to drain steadily out of a bathtub. After seconds, the water in the tub is cm deep. After seconds, the tub is empty. Write a linear function rule that models the depth of water in the tub y after any number of seconds x.

step-by-stp

the correct answer is the section c

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
