Answer:
The central angle of the arc is 288 degrees
Step-by-step explanation:
<u><em>The correct question is</em></u>
A circle has a circumference of 8. It has an arc of length 32/5 . What is the central angle of the arc,in the degrees?
we know that
The circumference of the circle subtend a central angle of 360 degrees
so
uing a proportion
Find out the central angle for an arc of length 32/5
If you divide 156 by 12 it'll give you 13, so there are 13 in each group
I think it's 100. You add all of the angles to =720. then solve for x. What you get for x, you plug into the equation for angle A and you should get 160-60=100.
3rd one I think tho it may not be accurate
