Sum of n terms in a geometric progression is given by Sn = a1 (1 - r^n) / (1 -r)
3( 1 - 4^6) / (1-4)
= 4,095
9 + 9 = 18
42 - 18 = 24
24 / 2 = 12
the length is 12 inches
Answer:
Therefore,

Step-by-step explanation:
Given:
0° < θ < 360°
tan θ = 3.5134
To Find:
θ in degrees = ?
Solution:
0° < θ < 360° .............Given
Means ' θ ' is between 0° and 360°
.............Given
Therefore,

Also,

So ' θ ' will have Two values for tan θ =3.5134

Therefore,
