Answer:

I think the answer might be true

Step-by-step explanation:

Supplementary angles add up to 180 degrees. When the angles are placed next to each other, they should add up to 180. Let's try it... 130+50 = 180. Therefore, these angles are supplementary.

Also, for extra help, 180-degree angles make a straight line, like this one. When you get stuck, you can always refer to websites such as Khan Academy for practice and explanations. (https://www.khanacademy.org)

for 5 if we are doing perimeter then it should be 23 and 35 for area

Step-by-step explanation:

perimeter- 5+4+6+6+2+5 = 28

area- (1/2(4)(3)) +(6·5) = 36

perimeter- 1+4+3+5+10 = 23

area- (1·5)+(3·10) =35

Here is the question!: Find the surface area of the following triangular prism.

Answers

Answer:

[tex]336\:\mathrm{ft^2}[/tex]

Step-by-step explanation:

The total surface area simply consists of three rectangles and two triangles. To find the total surface of the figure, find the sum of each of the shapes that make up the outside of the figure:

2 triangles: 2 x 1/2 x 6 x 8 = 48 ft^2

First rectangle: 6 x 12 = 72 ft^2

Second rectangle: 8 x 12 = 96 ft^2

Third rectangle: 10 x 12 = 120 ft^2

*Note: One of the dimensions is in yards, so make sure to convert it to ft (1 yd = 3ft)

Thus, the total surface area of the figure is 48+72+96+120 = 336 ft^2.

Step-by-step explanation:

Answer:

The answer is n=2.

Step-by-step explanation:

First, combine like terms, so the problem then looks like 3.6n-0.12=7.08.

Then, add 0.12 to both sides, which now looks like 3.6n=7.2.

Finally, divide both sides of the equation by 3.6, and the final answer is n=2.
