Answer: I’m pretty sure it’s 541.8
Step-by-step explanation:
Answer:
7
Step-by-step explanation:
If a, b and c are the lengths of a right triangle and c is the longest side, then:
We have a = 18cm, b = 24cm and c = 30cm. Substitute and check:
<h3>Answer: It's the right triangle.</h3>
We know that
a1=1
a2=3
a3=9
a2/a1=3/1----> 3
a3/a2=9/3----> 3
<span>common ration r is equal to 3
number of terms n is 12
The </span><span>Sum of geometric series is given by the formula
</span>Sum=a1*[1-r<span>^n]/[1-r]
</span>Sum=1*[1-3^12]/[1-3]-----> Sum=[1-3^12]/[1-3]----> [3^12-1]/[3-1]
<span>Sum=531440/2-----> 265720
the answer is
265720
