Answer: In degrees , The measure of 
In radians , the measure of 
.
Step-by-step explanation:
We know that the formula for length of arc is given by :-
, where 
= Central angle subtended by arc.
r= radius of the circle.
As per given , we have
Radius of circle : r=7 m
Length of arc : l= 8 m
Substitute these values in the above formula , we get
Hence, the measure of .
To convert it into degrees we multiply it with 
The measure of 
Hence, the measure of
Yes it is the same except there are two arcs you need to find the length for in this one.
Hello,
Let's assume n,n+1,n+2,n+3,n+4 the 5 numbers
n+(n+1)+...+(n+4)=5n+10=265
5n=265-10
5n=255
n=51
The 5th number is 51+4=55

Answer:
Step-by-step explanation:
Given that,
The sum of first n term of a sequence is
We need to find the sum of the first 5 terms.
Put n = 5,
So, the sum of first 5 terms is equal to 
.
