In F, < CFD = < DFE, m< BFA = 4x, m< AFE = 3x + 12, and BE and AC are diameters.

m arc DC=48°

Step-by-step explanation:

Angles in a Circle

We know and are diameters, so

.

Since and

We set the equation

Solving

Thus

We also know

Being opposite to

Then

It's divided in two equal angles , thus m arc DC is half of 96°:

m arc DC=48°

First option

step-by-step explanation:

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).
