Answer:
Use inverse cos to solve for x.
hope this helps
Answer:
x - 2 ≥ 0
Step-by-step explanation:
The expression under the square root cannot be negative, thus
x - 2 ≥ 0 , that is
x ≥ 2
To solve for the perimeter first figure out the length and width from the formula of area for the rectangle
A = LxW
A = (14-X)•X
L = (14-X)
W = X
P = 2L + 2W
P = 2(14-X) + 2(X)
P = 28 - 2X + 2X
P = 28.
The perimeter of the rectangle is A. 28.
1) From the picture, we see that we have two vertical angles:

2) Now, because of the<em> "Vertical Angles Postulate"</em> from geometry, we know that angles A and B are equal, so equalling the angles and replacing by their expression from above, we get the following equation in terms of x:

3) We must solve the last equation for x, doing that we find:

Steps to solve the equation
0) We have the equation:

1) We want all the terms with x on one side, and the other on the other one. So we pass the term +3x to the right as -3x:

2) Now we pass the term -10 to the left as +10:

3) We sum the terms on each side:

4) We pass the 3 that multiplies the x on the right, dividing the 60 on the left:

5) Finally we make the division and we get:

Answer
x = 20
Answer:
the last one
Step-by-step explanation:
multiply 100,000 times 0.35
and whatever you get add it to 100,000
