Given:

Center of the circle is O.

A and C are points on the circle.

The piece of the circle between the points A and C is called an arc.

Question 2.

AOC is a acute angle. It is located in a center of the circle.

Therefore AOC is a central angle.

labwork [276]

Answer:

120°

Step-by-step explanation:

$m\angle A = \frac{1}{2} \{(360 - 60) \degree - 60 \degree \} \\ \\ m\angle A = \frac{1}{2} \{300 \degree - 60 \degree \} \\ \\ m\angle A = \frac{1}{2} \{240\degree\} \\ \\ m\angle A = 120 \degree$

Hey can someone help me plz I don't know how to this?

So yes the board is wide enough. The are 10 decimeters in a meter.

What it is asking you to do in the example above is multiply 2.5/23.5 by 1.2 both top and bottom aka the numerator and denominator. This makes it easier to view and divide.

I didn't use this method I just looked at it but give it a try for your answer to B
