Answer:
x = 25
Step-by-step explanation:
To find the value of x we use the formula:
tan x° = opposite side /adjacent side
Opposite Side = 8
Adjacent Side = 17
tan x° = 8/17
tan x° = 0.4705882352941
of
x° = 25

Given:
The sum of two terms of GP is 6 and that of first four terms is
To find:
The sum of first six terms.
Solution:
We have,
Sum of first n terms of a GP is
...(i)
Putting n=2, we get
...(ii)
Putting n=4, we get
(Using (ii))
Divide both sides by 6.
Taking square root on both sides, we get
Case 1: If r is positive, then using (ii) we get
The sum of first 6 terms is
Case 2: If r is negative, then using (ii) we get
The sum of first 6 terms is
Therefore, the sum of the first six terms is 7.875.
