What is the measure of the unknown angle?
A. 60°
B. 63°
C. 64°
D. 70°

Answer:
B. 63°
Step-by-step explanation:
The distance around a circle is 360°
This means that 297° + n = 360°
Equation:
297 + n = 360
We can find the value of n by subtracting:
297 + n = 360
-297 -297
n = 63
Therefore, the value of n is 63 degrees.
