Select 3 ratios that are equivalent to 7: 6

21:18, 14:12, and 28:24

Step-by-step explanation:

In order to keep the ratio equivalent, you have to multiply both numbers in the ratio by the same number. For instance, if the ratio was 1:1, in order to keep the ratio equivalent, I'd have to multiply both numbers by 2, 3, 4, etc.

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
