Please Help Write an equation for the nth term of the arithmetic sequence 47, 38, 29, 20,

An equation for the nth term of the arithmetic sequence is

-9

Step-by-step explanation:

They all follow the same sequence such as -9 for ex 47-9 is 38

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
