Answer:
Cos A = x/z
Step-by-step explanation:
You need to memorize the definitions of all the trig functions and then these types of problems become easy! OK?
Cos = adjacent side/hypotenuse
Cos A = x/z
So we are given the area, length and need to find the width
to find the width
width = area / length
so to plug in what we know
width = 5/8 divided by 10
width = 1/16
Hope this helps :)
Answer:

Step-by-step explanation:
First determine her savings
560-347.49
212.51
Then divide by the total amount
212.51/560
.379482143
Change to percent form
37.948%
The answer is -3. Adding a negative onto a positive is just like subtracting from the positive. So, first off, 5+(-3) is 2. Then, subtracting 6 from the 2 will give you a negative number, -4. Subtracting a negative changes the sign to be a plus, so you plus one onto the -4. This leaves you with the answer of -3.
Correct Answer: 
We are to find:

Multiplying and simplifying the radicals, we get:
