Answer:
<u>∠DFA = 82°</u>
Step-by-step explanation:
According the property of inscribed angles and arcs, the angle is half of the arc length.
Solving :
- ∠CFB = 1/2 x ∡CB
- ∠CFB = 1/2 x 164°
- ∠CFB = 82°
- ∠CFB = ∠DFA (Vertically Opposite Angles)
- <u>∠DFA = 82°</u>

Step-by-step explanation:
Answer: C $1.51
To solve this, start with a proportion. Put the CPI numbers on the left and the apple juice prices on the right.
You will have:
82.4/130.7 = 0.95/x
Cross multiply to solve and you will get the price of the juice is $1.51.
