Answer: x = 35

Final answer: 40, 105, 35.  

Answer: x = 35

So, it would be  40, 3(35), and 35.

Final answer: 40, 105, 35.  

First, we know that sum of angle measure 180.

So, algebraically, we can put out this equation.

40 + 3x + x = 180

Now we solve

Step-by-step explanation:

Given: 40+ 3x + x = 180

The whole goal is to isolate x. Remember DCMAM: Distribute, combine, move variable to one side to another, add/subtract, divide/multiply

There is no distribution, so move on.

We do have to combine 3x with x

40 + 4x = 180.

Now move 40 to the right side.

40 + 4x = 180

-40            -40

4x =  140

Now divide 140 by four

4x/4 = 140/4

x = 35

So, it would be  40, 3(35), and 35.

Final answer: 40, 105, 35.

Hope this helps.

Answer:

X=140/3

Step-by-step explanation:

180-40=140, 140 divided by 3 is 140/3, so 40+3x140/3=180

16. A can in the shape of a cylinder has a diameter of 6 centimeters
sladkih [1.3K]

Answer:

surface area = 245.04 cm² (nearest tenth)

Step-by-step explanation:

Surface area of a closed cylinder = 2\pi r^2+2\pi rh

Given:

  • diameter = 6 cm ⇒ radius = 3 cm
  • height = 10 cm

⇒ surface area = 2 × \pi × 3² + 2 × \pi × 3 × 10

                          = 78\pi

                          = 245.04 cm² (nearest tenth)

Answer:

  3.0

Step-by-step explanation:

The angle, its opposite side, and the hypotenuse are given. Then the relevant trig relation is ...

  Sin = Opposite/Hypotenuse

  sin(21°) = x/8.3 . . . . . . . . . . . . . . . . . . use the given values

  x = 8.3·sin(21°) ≈ 8.3×0.3584 . . . . . . multiply by 8.3

  x ≈ 3.0
