Answer:
A is 60°, B is 300°
Step-by-step explanation:
If you look closely, you can tell that this circle is divided into 6 triangles, but there is only one showing. This triangle is 1/6 of the circle.
You can find B by find 1/6 of 360° and subtracting that from 360, (a full circle is 360°)
1/6 of 360° is 60°
360° - 60° = 300°, so B is 300°
Now lets find A. Triangles are 180°. This triangle is obviously an equilateral triangle, so the measurements will all be the same.
180 ÷ 3 is 60, so A is 60°
