Z = √(10^2 + 8^2 - 2 *10 * 8 * cos(z)
z = arccos(1/8
A = 82.8
Answer is D.
In any right triangle with a 45 degree angle. The hypotenuse is the length of the side times √2
The answer is 8√2
X^2-2x-3
x^2+x-3x-3
x(x+1)-3(x+1)
(x-3)(x+1)
...
x^2-5x-6
x^2+x-6x-6
x(x+1)-6(x+1)
(x-6)(x+1)
So the common factor is (x+1)
You have two totals: total # of bills and total amount of $. Using x as #of 20s, and y as # of 50s, you can use the system
x+y=18
20x+50y=450
<span>The given expression can be classified in many ways. To summarize, there are a few ways to classify it:
