Answer:

x = 25°

Step-by-step explanation:

3x + 2x + x + 30° = 180°

6x + 30° = 180°

6x = 150°

x =25°

=> 3x = 25 * 3 = 75°

=> 2x = 25 * 2 = 50°

=> x + 30° = 25° + 30° = 55°

I can’t figure this out I need the answer
fredd [130]

Answer:

  • Area 2 = 72 cm²
  • CD = 7 cm

Step-by-step explanation:

For similar figures, side lengths (and any other linear measure) are proportional. Areas are proportional to the square of the scale factor for side lengths.

  Perimeter 1/Perimeter 2 = CD/EF

  21/18 = CD/6

  CD = 6(21/18)

  CD = 7 . . . cm

__

  Area 2/Area 1 = (Perimeter 2/Perimeter 1)²

  Area 2/98 = (18/21)²

  Area 2 = 98(6/7)²

  Area 2 = 72 . . . cm²

-4 1/2 x -3 3/4 <br> Does anyone know how to get the answer to that
taurus [48]
Hello there! Given the equation, we can solve through a series of steps:

1. Convert

In this step, we convert the mixed numbers to make them improper:

2 x 4 + 1 = 9, which means -4 1/2 = -9/2

4 x 3 + 3 = 15, which means -3 3/4 = -15/4

2. Multiply

Now that we have the improper fractions, we can multiply accordingly:

(-9/2 • -15/4) = -135/8

3. Simplify

Since we have our result, we can simplify to a mixed number:

-135/8 = 16 7/8

Your final answer is 16 7/8. Hope this helps!
