3 The area of the rectangle shown is 375 square centimeters. h
25 cm
What is h, the height of the rectangle in centimeters?
F 350 cm
G 7.5 cm
H 15 cm
J 162.5 cm

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
