Step-by-step explanation:

I drew a diagram on paper but cant here soooo....

but math checks out i think.

Angles AOD and COB are both 36.

Angles AOC and DOB are both 144.

DOB has to be 4 times angle COB, right? if so, then:

144 = 4*36. That checks out. Now to see if all the angles combined are 360.

36 + 36 + 144 + 144 =360. It works!

This is my first answer ever btw so if the formatting and grammar is bad im sorry.

So to put them in intervals of 5 you would have:
70-74
75-79
80-84
85-89
90-94
95-99
In these intervals you would have:
70-74: 72
75-79: 78
80-84: 81
85-89: 86, 86, 87
90-94: 92, 92, 92
95-99: 98

The second interval is 75-79 where there is only one number. Therefore the frequency will be 1.
The correct answer is A. Hope this helps! :)
