Do it for me! i need both of this questions

Whoa, that's a lot to answer...

15. 30000=500x

16. y=58x+5

in 16, the total cost is y, so y has to be in 1 side for itself. and we need to add the amount of tickets and the fee (5$). So we get that equation.

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
