Answer:

Step-by-step explanation:
Here, we have the known angle sandwiched between two known sides.
So, we have SAS.
And we want to find the side opposite to the angle.
Therefore, we can use the Law of Cosines:

Again, it is important what we substitute.
a and b are the two side lengths. So, we will substitute 8 for a and 13 for b.
C is our angle. So, substitute 64 for C.
And c is what we’re trying to solve.
Therefore:

Simplify:

Add:

Take the square root of both sides:

Use a calculator. So, c is approximately:

The c is our y. So, y is approximately 11.9 units.
For the $210 one: $30/g
For the $264 one: $33/g
Therefore, the $210 one is a better deal.

Step-by-step explanation:
As I have explained in the picture, all they are asking is for you to input 2 wherever there is an x.
Hello there!
Jenny wants to park in an airport parking lot. The parking lot costs x amount of money per hour, plus an additional parking fee of $10. Jenny stays in the parking lot for 3 hours.
This causes our equation to be 3x (3 hours) + 10 (additional parking fee).
I hope this helps!
1-6x=x+14 so that means x=14/-5 i think
