The ratio of the number of cars to the number of motorcycles in a parking lot is 10 : 3 . The ratio of the number of motorcycles to the number of vans is 9 : 5 . There are 30 vans in the parking lot. How many more cars than vans are there?

f(x)=4

step-by-step explanation:

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

5: 20
