I need to see something before I give the answer.
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
Answer:
C. -31
Step-by-step explanation:
To solve this problem, first you have to order of operations stands for PARENTHESIS, EXPONENTS, MULTIPLY, DIVIDE, ADD, and SUBTRACT the numbers from left to right. Please Excuse My Dear Aunt Sally!
First, parenthesis.
(4+2)=6
5-6²
Then, exponent.
6²=6*6=36
5-36
Subtract numbers from left to right.
5-36=-31
As a result, the correct answer is -31.
