Mrs. jeffries has 12 girls out of 16 students on the student council. The earth day committee has 4 girls out of the 8.Are the ratios equivalent?

not equivalent.

Step-by-step explanation:

other answer is correct. i had used the radius of the radius somehow. a website:

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh
