A rectangle has a length that is 8 less than its width, w. The perimeter is 52. Which equation can be used to determine its width? 8 minus w = 52 2 (w minus 8) + 2 w = 52 (w minus 8) + w = 52 2 (8 minus w) + 2 w = 52

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

isosceles obtuse
