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: C
Step-by-step explanation:


Divide them both it should give you the awnser
It would be 6.875 i do believe
The vertical distance between Dean and Jeff is 13 ft below the surface
Explanation:
Jeff dove 39 ft below the surface and then ascends 18 ft
-39 - 18 = 21
Jeff is 21 ft below the surface
------------------
Dean is 34 ft below the surface
-34 - (-21) = -13 ft
-----------------
So, Dean and Jeff are 13 feet away from each other (vertical distance).
