Question

The measure of angle BAC is 18 ° . What is the measure of its intercepted arc BC? A. 9 ° B. 36 ° C. 18 ° D. 56.52 °

Answer 1

To find the measure of the intercepted arc BC when the measure of angle BAC is 18°, you can use the fact that in a circle, the measure of an inscribed angle is equal to half the measure of the intercepted arc.

So, if angle BAC is 18°, then the measure of the intercepted arc BC is:

\(18° \times 2 = 36°\)

So, the measure of intercepted arc BC is 36°, which corresponds to option B.
