Which equation below represents the model shown?

The answer is A.

Step-by-step explanation:

This is quite the odd question to see on homework, but looking at it a certain way helps determine the answer. two fourths are shaded in, and so is one twelfth. Since the other five twelfths are blank, it can be interpreted that the model is showing us A. This can be checked on a scientific calculator.

.5 / (1/12) = 6

Therefore, A is correct.

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
