Answer: , where n is a natural number.
Step-by-step explanation:
A series can be represented in a summation or sigma notation.
Greek capital letter, ∑ (sigma), is used to represent the sum.
For example: , where n is a natural number.
The given series : 1,4,9,16 which can be written as .
So , we can write it as
, where n is a natural number.
Answer: The measure of ∠ABC = 54°.
Step-by-step explanation:
As we know that
Measure of major arc AC = 234° ( Far arc)
Measure of minor arc AC = 126° (Near arc)
By theorem, we know that the angle formed by intersection of two tangents is equal to half the difference of far arc and near arc.
As we know that ∠ABC is given by
Hence, the measure of ∠ABC = 54°.
