Answer:
Step-by-step explanation:
How can you remember the formula?
Well, it helps to know it's the Pythagoras Theorem with something extra so it works for all triangles:
Pythagoras Theorem:
(only for Right-Angled Triangles) a2 + b2 = c2
Law of Cosines:
(for all triangles) a2 + b2 − 2ab cos(C) = c2
So, to remember it:
think "abc": a2 + b2 = c2,
then a 2nd "abc": 2ab cos(C),
and put them together: a2 + b2 − 2ab cos(C) = c2

5 feet = ?
5*12 = 60
Answer:
4
Step-by-step explanation:
First, you would have to prime factorize both of the numbers. The prime factorization of 24 is 24 = 2*2*3*3, and the prime factorization of 32 is 32 = 2*2*2*2*2 or 2^5. After that, you would find what is most common:
24 = 2*2*3*3
32 = 2*2*2*2*2
What is common is that there is two 2's in each equation. 2*2 is 4, so the answer is 4.
