Answer:

A. m(arc BC) = 16°

B. m(arc BAC) = 344°

Explanation:

From the picture attached,

AB is the diameter of the circle.

Since, measure of an arc is always same as the central angle of arc.

Therefore, m(arc AC) = m(∠ADC) = 164°

m(arc AB) = 180°

m(arc BC) = 360° - m(arc AB) + m(arc AC)

= 360° - (180° + 164°)

= 360° - 344°

= 16°

m(arc BAC) = m(arc AB) + m(arc AC)

= 180° + 164°

= 344°
