Use inductive reasoning to predict the next number in the list
6,1,5,0,4,-1,3

you can use a^2+ b^2=c^2

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

answer is  

a.

5.56

hope you get this right.
