Answer:
A. m(arc BC) = 16°
B. m(arc BAC) = 344°
Step-by-step 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°

Answer: A
Step-by-step explanation: took the test, got it right.
Answer:
In steps
Step-by-step explanation:
ΔABE ~ ΔACD
AB / AC = BE / CD
3 / 9 = 7 / CD
CD = (9 x 7) / 3 = 63 / 3 = 21
