Solve using the Pythagorean theorem.
The hypotenuse is c.
Answer:
The answer is 
Step-by-step explanation:
We have to:

So, if we take the 60 degree angle of the smallest triangle, we have to:

We do not know x. But if we take the sine of the angle of 30 degrees and the main triangle we have:

Then:



A. 12•8=96, 96/2=48, 48•4=192, 12•12=144, 192+144=336
Answer:
2730
Step-by-step explanation:
We want to determine the greatest common divisor of the elements of the set 
We apply the Fermat's little theorem which states that if p is a prime number, then for any integer a, the number aᵖ − a is an integer multiple of p.
Now,
if p-1 divides 12.
Since the of 12 are 1,2,3,4, 6, 12, the corresponding primes are 2, 3, 5, 7, 13.
Therefore, the gcd of the elements in
and 
2*3*5*7*13=2730
Therefore, the gcd of the elements in set S is 2730.
4/12=1/3
8/14=4/7
6/8=3/4
3/6=1/2
5/15=1/3
