Answer:
You cannot solve by factoring
Step-by-step explanation:
We want to solve by factoring.
We can rewrite as:
So we have a quadratic equation in .
We split the middle term to get:
We look for factors -28 that sum up to -6
This is not possible hence the given equation is not factorable
The arc length of AB is 8 m (app.)
Explanation:
Given that the radius of the circle is 8 m.
The central angle is 60°
We need to determine the arc length of AB
The arc length of AB can be determined using the formula,
Substituting central angle = 60° and circumference = 2πr in the above formula, we get,
Simplifying the terms, we get,
Dividing, we get,
Hence, the arc length is approximately equal to 8.
Therefore, the arc length of AB is 8 m
