Answer:
The radius is 60 degree so the whole diameter will be 120 degree now find the arc
Step-by-step explanation:
The sequence above is an arithmetic sequence
For an nth term in an arithmetic sequence
A(n) = a + ( n - 1)d
where a is the first term
n is the number of terms
d is the common difference
From the question
a = - 1
To find the common difference subtract the previous term from the next term
We have
d = 4 --1 = 4 + 1 = 5 or 9 - 4 = 5
Therefore d = 5
Substitute the values into the general formula
That's
To find A(50) substitute the value of n that's 50 into the formula above

The angle is 64 because if srt is 26 then urt is also 26 because the kite is symmetrical. In a symmetrical kite the intersecting lines form right angles so we can say that urt +rus=90
So 26+ rus =90
Rus=64
