The number is (2√3) / 3
To find the missing number, convert what it says in words to an equation:
Divide both sides by 15:
Take the square root:
Answer:
Step-by-step explanation:
tan7=h/820
h=820tan7
h=101m
This problem can be solved using dimensional analysis.
The sum of the convergent series is 5.31
For given question,
We have been given a series
We need to find the sum of given convergent series.
Given series is a geometric series with ratio r = sin(1)
The first term of the given geometric series is
So, the sum is,
=
= sin(1) / [1 - sin(1)]
This means, the series converges to sin(1) / [1 - sin(1)]
=
=
=
= 5.31
Therefore, the sum of the convergent series is 5.31
