Well that's quite easy. There is a short cut. So 12 divided by 2 is 4. Then 6 divided by 2 is 3. There is a thing called a Pythagorean Triple. And the first one is 3,4 (which is the missing side) and 5. That is the most commonly used set and so are the number's multiples. Therefore the missing leg's length is 4 centimeters.
Answer:
=6665
Step-by-step explanation:
The sum of a geometric series is given by:
Sn=a(1-rⁿ)/(1-r)
Sn is the sum of the first n terms, r is the rate and n is the number of terms.
r the quotient between any two consecutive numbers.
r=6/-1= -6
Sn=-1(1-(-6)⁶)/(1--6)
=46655/7
=6665
Sum of the first six terms=6665
