Answer: 
Step-by-step explanation:
The missing figure is attached.
The perimeter of a rectangle is:

Where "l" is the lenght and "w" is the width.
You can identify in the figure that:

Then, knowing the perimeter of the rectangle, you can make the subsitution into the formula:

Now you must simplify and solve for "z"

Finally, substituting the value of "z" into
, you get:

Answer:
Step-by-step explanation:
m∠AOC = 180 as it is straight line
m∠AOC = m∠AOB + m∠BOC
m∠AOB + m∠BOC = 180
3x + 124 + 6x + 29 = 180
9x + 153 = 180
9x = 180 - 153
9x = 27
x = 27/9
x = 3
m∠BOC = 6x +29 = 6*3 + 29 = 18 +29 = 47
Collect the like terms
3x+13x=16x
16x+8y
Answer:
D, 1890 M 2
Step-by-step explanation:
45 x 42 = 1890
as a 3d shape, this would be m3
but because its flat, 2d, its m2
