For the first part, the answer is choice B) 360. This applies to any polygon and it doesn't have to be an octagon. The sum of the exterior angles of any polygon is always 360 degrees. This is something you should memorize or have on a reference sheet.

For the second part, the answer is choice C) 142 degrees. We have a parallelogram (specifically a rhombus but that doesn't matter) so the adjacent angles are supplementary. This means they add to 180 degrees. Solving x+38 = 180 leads to x = 142

What is m∠G ?<br><br> Enter your answer in the box.
Elena-2011 [213]
We are given all the angle measures, therefore we can equate all the expressions to 180 degrees. We can do this by using the Triangle Angle Sum Theorem, which states that all triangles' interior angles add up to 180 degrees. After we do that, we get:
x + 3x + 25 + x - 5 = 180
Now, just solve for x:
x + 3x + 25 + x - 5 = 180
5x + 20 = 180
5x = 160
x = 32
We've found the value of x, but the question asks us the measure of angle G. We can find the angle measure by substituting 32 into the expression for angle G. Doing so and simplifying gives us 121 degrees. Therefore, the measure of angle G is 121 degrees. Hope my answer has come of aid to you and have a great day!

What is 7x + 6x = ?<br>​
viva [34]

Answer:

  • 13x

Step-by-step explanation:

<u>Two ways to solve</u>

1.) Expand each term in the equation

  • 7x = x · x · x · x · x · x · x
  • 6x = x · x · x · x · x · x
  • Count all the x’s ⇒ There are 13 x’s ⇒ 13x

2.) Add the coefficients

  • 7 + 6 = 13
  • 7x + 6x = 13x

Hence,

Answer = 13x

A mason's assistant's rate of pay is $0.95 per cubic foot of earth moved. he digs a trench 2.5 ft. wide by 2 ft. deep by 150 ft.
Romashka [77]
Well well if he gets paid. $0.95 per ft^3 this equates to:
pay = $0.95 * volume

because the volume is the amount of ft^3

a trench shape would be considered rectangular. The the volume of rectangle is :
volume = length * width * height

so:
v = 2.5 ft * 2 ft * 150 ft
v = 750 ft^3

so:
pay = 0.95 $/ft^3 * 750 ft^3

p = $712.50
