Answer:
12
Step-by-step explanation:
4 times 8 =32, 32 - 20= 12
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

interior means inside of the parallel lines l and m
The alternate interior angles are 4 and 5
and 3 and 8
