Answer:
Step-by-step explanation:
Given is a picture of circle with angle
BOC =7x-11
Also angle of arc BC = angle BOC = 3x+53
Since both are the same equate the two

Now substitute this x value in any one of 3x+53 or 7x-11
Angle COB = angle BOC = 3x+53
= 48+53 = 101 degrees
-------------------------
To find length of arc
Central angle = 101
Hence arc lengh =
Answer:
40
Step-by-step explanation:
Do 60 × 10.00 to get 600. Then do 800-600 to get 200. Then do 200÷5.00 to get 40.
