Answer:
30°
Step-by-step explanation:
If chord AB subtends two arcs with measures in the ratio of 1:5, then the measure of minor arc is x and the measure of major arc is 5x. Thus,

Thus, the measure of the angle AOB is 60°. Consider isosceles triangle AOB (because AO=BO=radius of the circle). The angles adjacent to the base AB are congruent, thus

Since line CD is tangent to the circle,

Hence,

The answer is a because it is saying the corrext answer to the question
Answer:
Ethan can type 6 pages before meeting starts.
Step-by-step explanation:
Given that,
Ethan can type 2 pages in 1/8 hours
and his meeting is 3/4 hours late.
To find,
number of pages Ethan can type in 3/4 hours
<h3>1) </h3><h3>convert hours to minutes</h3>
1 hour = 60 minutes
1/8 hours = 1/8 * 60
= 7.5 minutes
3/4 hours = 3/4 * 60
= 45 minutes
<h3>2) </h3><h3>calculate pages typed</h3>
7.5 minutes = 1 page typed
1 minute = 1/7.5 pages typed
45 minutes = (1/7.5) * 45
= 6 pages typed
