Answer:
Part 1) arc AB=110°
Part 2) m∠BOC=36°
Part 3) arc ADC=214°
Explanation:
we know that
Central angle is the angle that has its vertex in the center of the circumference and the sides are radii of it.
Part 1) Find the measure of arc AB
we know that
The measurement of the arc AB is that of the central angle AOB
m∠AOB=arc AB -----> by central angle
we have
m∠AOB=110°
therefore
arc AB=110°
Part 2) Find the measure of angle BOC
we know that
The measurement of the arc BC is that of the central angle BOC
m∠BOC=arc BC -----> by central angle
we have
arc BC=36°
therefore
m∠BOC=36°
Part 3) Find the measure of arc ADC
we know that
arc ADC+arc BC+arc AB=360° ------> by complete circle
we have
arc BC=36°
arc AB=110°
substitute
arc ADC+36°+110°=360°
arc ADC+146°=360°
arc ADC=360°-146°=214°
