Write and solve a proportion that the teacher can use to estimate how many students in the whole school would choose the aquarium. Show your work. (i think you will need the photo attached to solve)

step-by-step explanation:

one triangle is 2.5 times bigger than the other triangle.

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
