(3x +20)

Mathematics
1 answer:
Rashid [163]2 years ago
4 0

Answer:

x = 20°

Step-by-step explanation:

The angle opposite to 3x + 20 is also 3x + 20     (opposite interior angles)

The angle opposite to 5x is also 5x                      (opposite interior angles)

Solve:

Set up the equation by adding all the angles. The sum of these angles should equal 360.

  • (3x + 20) + (3x + 20) + (5x) + (5x) = 360
  • 16x + 40 = 360
  • 16x = 320
  • x = 20

x = 20°

Hey there!

I believe your answer would be a transformation, and not a translation.

A transformation is an operation that moves, flips, or otherwise changes a figure to create a new figure.

Hope this helps!

Have a wonderful day! :)

I’d say it’s 2/1 since the rise is 2 and the run is 1 and slope I believe is rise/run. It’s been awhile So I’m not too sure this is the right answer. I hope it is.

A Rectangular has area 12a^2 and perimeter 14a what are the dimensions of this Rectangular?​
Nataliya [291]

9514 1404 393

Answer:

  3a by 4a

Step-by-step explanation:

For dimensions L and W, the area and perimeter are ...

  A = LW = 12a^2

  P = 2(L+W) = 14a

Using the second equation, we can find L:

  L +W = 7a . . . . . divide by 2

  L = 7a -W

Substituting into the area formula gives the quadratic ...

  (7a -W)(W) = 12a^2

  W^2 -7aW +12a^2 = 0 . . . . arrange in standard form

  (W -3a)(W -4a) = 0 . . . . . . . factor (find factors of 12 that total 7)

Then we have the two solutions ...

  W = 3a, L = 4a

  W = 4a, L = 3a

The rectangle dimensions are 3a by 4a.
