Answer:
The correct answer is second option 60°
Step-by-step explanation:
From the figure we can write,
measure of arc AEC = measure of arc AE + measure of CE
measure of arc ACE = measure of AC + measure of CE
measure of arc AEC + measure of arc ACE = 280 + 140 = 420°
measure of arc AE + measure of CE + measure of AC + measure of CE = 420
measure of arc AE + measure of CE + measure of AC = 360°
measure of CE = 420 - 360 = 60°
The correct answer is second option 60°

plug in x = -1 to both sides and you get 1 as the answer for both sides.
The radius of the sector is 10.27 miles
<h3>How to find the radius of a sector?</h3>
The area of a sector can be represented as follows;
area of a sector = ∅ / 360 × πr²
where
- r = radius
- ∅ = central angle
Therefore,
∅= 25 degrees
area of the sector = 23 miles²
area of a sector = ∅ / 360 × πr²
23 = 25 / 360 × πr²
cross multiply
23 × 360 = 25πr²
8280 = 25πr²
divide both sides by 25
πr² = 8280 / 25
πr² = 331.2
r² = 331.2 / 3.14
r² = 105.477707006
r = √105.477707006
r = 10.2702336877 miles
Therefore, the radius of the sector is 10.27 miles
