Need help asap rocky :))

The value of ∠EOF is 75°.

Step-by-step explanation:

Let us take O be the center of the circle.

Given,

∠AOB = 45°

∠COD = 60°

To find the ∠EOF (value of x)

Now,

Since AD is the diameter of the circle, ∠AOD = 180°

∠AOB+∠COD+∠BOC = ∠AOD

Or, 45°+60°+∠BOC = 180°

or, ∠BOC  = 180°-(45°+60°)

= 75°

Again,

∠BOC  = ∠EOF as they are vertically opposite angle.

Hence,

∠EOF = 75°

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

hope this : )

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
