How do you find the measure of this angle ?
1 answer:
The lines through the sides in the circle indicate that the three sides are all of the same length, and therefore share the same angle.
A shape inside a circle will always have its angles equal 360, so you can find the individual angle with the following equation:
Subtract 120 from both sides.
Divide both sides by 3.
mBC's angle is 80 degrees.
