Find missing integer
2( )=18

9

Step-by-step explanation:

2 ( ) = 18

Remember that bracket sign means multiplication. So, if we divide both sides by 2, we have

( ) = 18/2

( ) = 9

The missing integer is 9

the correct answer would be 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
