Answer:

The angles on the top form 180 degrees, a line. So, 180 = 4x + 72 which gives you x = 27 Angle BFC is 66 degrees, angle CFD is 54 degrees, and angle BFA is 29 degrees. Therefore, C. 27 degrees is not a measure of an angle in the figure

Answer:

c) 27°

Step-by-step explanation:

Step 1: Find the value of x

All angles on a straight line are equal to 180 degrees.

Therefore,

60 + 2x + (2x+12) = 180

72 + 4x = 180

4x = 108

x = 27°

Step 2: Through the value of x, calculate all angles

2x = 27 (2) = 54°

2x + 12 = 2 (27) + 12 = 66°

x + 2 = 27 + 2 = 29°

27° is not a measure of an angle in the figure.

Therefore, option c is the correct answer.

Find the surface area of a square prism with a side measure of 6.

Vesnalui [34]

The surface area of any solid is the summation of all the areas of its faces. For a square prism, the surface area is therefore calculated through the equation,
A = 6e²
where A is area and e is the measure of the side.

From the given above, it is stated that the edge of the prism measures 6. Substituting this value to the equation above,
A = (6)(6²)
A = 216
Therefore, the surface area of the given prism is equal to 216 square units.

Answer:

$1200.

Step-by-step explanation:

We have been given that Kiersten runs a website that helps people learn programming. Every month, Kiersten receives a subscription fee of $10 from each of the subscribers to her website.

Let us find number of subscriber that will pay this month Kiersten for her online business.

Last month, the website had 100 subscribers. This month, 30 new members joined the website, and 10 members cancelled their subscription, therefore, number of subscriber this month will be $100+30-10=130-10=120$ subscribers.
