You would pay $1100.15 (rounded to nearest hundredths)(unrounded would be 1100.14875)
Answer:
Last Option
Step-by-step explanation:
We have a triangle and we know its three sides.
We want to find one of your anguos. Then we use the cosine theorem.

Where

Now we solve for x from the equation

We know the distance formula is

9)
Here A( -4,2) and B(1,4)
So length of AB
= 
Also C(2,1)
Length of BC
= 
So we can see that length of AB is not equal to length of BC
11.
Now AB = 
Also C(2,-1) & D(4,4)
Length of CD
= 
Yes AB = CD
The answer for this is 51
25 + 2•13
25 + 26
51
