Answer:
114°
Step-by-step explanation:
The measure of an arc is double the measure of the angle between the chord and the tangent line.
= 9n + 63
generate the first few terms using the recursive equation
f(1) = 72
f(2) = 72 + 9 = 81
f(3) = 81 + 9 = 90
f(4) = 90 + 9 = 99
the sequence is 72, 81, 90, 99, .....
This is an arithmetic sequence whose n th term formula is
= + (n - 1 )d
where is the first term and d the common difference
d = 99 - 90 = 90 - 81 = 81 - 72 = 9 and = 72
= 72 + 9(n - 1) = 72 + 9n - 9 = 9n + 63 ← explicit formula
A mixed number is a whole number plus a fraction.
575 is just a whole number, without a fraction. If you absolutely must have
a mixed number, then you have to create a fraction out of 575 somehow.
This is going to look pretty silly, but I guess you could take ' 1 ' away from 575,
and use it to make a fraction, like 1/1 .
Then your mixed number could be 574 and 1/1 .
Isn't that ridiculous ? ! ?
