1. Which of following situations does not represent a proportional relationship?

a. Emilia earns $8.75 an hour and 10% commission on any new memberships she
sells.
b. Tatum is flying a remote-controlled airplane at a speed of 18 miles per hour.
c. Phoebe is at a baseball game where they sell all drinks for $1.75 each.
d. All of the above are proportional.

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

b, 20 yards
