Answer:
76 degrees.
Step-by-step explanation:
Let as consider O is the center of the circle . So from the figure it is clear that
By central angle theorem, central angle subtended by an arc is twice of inscribed angle of the same arc.
We know that, 
and angle BOD is the central angle subtended by arc BD.
Now,
Therefore, the measure of arc BC is 76 degrees.
Answer:
18
Step-by-step explanation:
We can use a proportion to find out the number of teachers that are needed.
3/70 = x/14,700
70x = 3 * 14,700
70x = 44,100
x = 630
630 teachers are needed altogether. Since there are already 612 teachers, the number of more teachers who are needed is the difference between 630 and 612.
630 - 612 = 18
