Answer: 1/6
Explanation:
The question is asking how much of the whole circumference is arc AB given that it's central angle is 60°. We can see that the angle is of the whole. This means that if there were 360 equal sectors, or slices, of the circle, then this angle would take 60 of them.
From this, we can see that if the circumference was divided into 360 equal parts, then the arc would also take up 60 of them, making the arc , or .
We could have alternatively seen that the ratio of arc length to the whole circumference would be the same as the ratio of the central angle to the "whole angle" or 360°.
Putting in 60 for the central angle, we get
The question is asking what fraction of the circumference is the arc length, so let's isolate the arc length by multiplying the circumference to both sides
This equation in words says that the arc length is one sixth of the circumference, which is exactly what the question is asking.
The major product of this reaction which is the oximercuration - demercuration reaction is explained.
<h3>What is a chemical reaction?</h3>
It should be noted that a chemical reaction simply means a process that leads to the transformation of a as of chemical substances to another chemical substance.
The steps in the reaction include:
- The nucleophilic bond attack.
- The formation of oxonium ion.
- Deprotonation of the oxonium ion.
- NaBH4 replaces the acetoxy mercury.
Here, alkene is converted into alcohol.

The correct answer is: Area of △ABC = 20Explanation:Since the area of △AOD = 10; therefore. the area of <span>△BOC is also 10.
Now:
The area of </span>△ABC = Area of △AOB + Area of <span>△BOC --- (1)
Since Area of </span>△AOB =
(Area of <span>△ABC) --- (2)
Plug (2) in (1):
(1) => Area of </span>△ABC =
(Area of △ABC) + 10
=>
(Area of △ABC) = 10
=> (Area of △ABC) =
20<span>-i
