Answer: A. They are both incorrect
Step-by-step explanation:
x=3√2
y=6
z=3√2
-----------------------
45-45-90=1:1:√2
------------------------
solve for x
x is the side accordingly to 90 in the smaller triangle, so it should be the [45] side times √2
3×√2=3√2
-----------------------
solve for y
y is the side accordingly to 90, so it should be the [45] side times √2
3√2×√2=6
----------------------
solve for z
z is the side accordingly to 45 in the bigger triangle, x is also accordingly to 45 in the bigger triangle
z=x
z=3√2
Answer:
a.2010 rad/min
b.2412 feet/min
Step-by-step explanation:
We are given that
Diameter of wheel,d=2.4 feet
Radius,r=
a.Rate=320 rev/minute
1 rev=
radian
320 rev/minute=
Where 
Angular speed=
b.Speed,v=

A, because there is no slope or change in the line, meaning it is constant, or, if you will, has a rate of change of 0
<span>5(n-6)-2=2n-5
5n-30-2 = 2n-5
5n - 2n = 30+2-5
3n = 27
n = 27/3
n = 9
So, your final answer is 9
Hope this helps!

Answer:
See below
Step-by-step explanation:
Here I attach you the detailed solution.
For this we will need to use the following trigonometric properties and formulas:
sin (x-y) = sin (x) cos (y) - cos (x) sin (y)
tan(x) = sin(x)/cos(x)
cot(x) = 1/tan(x) = [tan(x)] ^(-1) = cos (x)/sin(x)
This properties can be found in any mathematics book and is valid to apply them here, and are the only tools we use to solve the problem. Its worth to note that we have to assume that cos(x)sin(y) is different from 0 in order to use it as a denominator.
