Identify the polynomial.

a 2 - b + c - d 3

it has to have an angle of 90 degrees

25.3

step-by-step explanation:

1st step

add 3+6

=9

multipy 9*3

=37

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
