Answer:
<h3>
s = 16.2 units</h3><h3>
</h3>
Step-by-step explanation:
use Pythagorean theorem:
a² + b² = c²
where a = 12/2 = 6
b = 15
c = s
<u>plugin values into the formula:</u>
6² + 15² = s²
s = √(6² + 15²)
s = √261
s = 16.2 units
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
