Answer:

14/27

Step-by-step explanation:

Let x be the unknown number

-2/3 * x = -28/81

Multiply each side by -3/2

-3/2*-2/3 * x = -28/81 * -3/2

x = 28/2 * 3/81

x =14*1/27

x = 14/27

Answer:

Option A= 250

Step-by-step explanation:

Coterminal angles are angles in standard positions having thesame terminal .

Coterminal angles are always negative and positive.

For example:

The coterminal angle of 30° is-

30 - 360 = -330

30 + 360 = 390

Therefore, -330 and 390 are coterminal.

So, to the question:

The angles between 0 -360 coterminal to -110 is 250.

Prove:

250 - 360 = -110

250 + 360 = 610

Option A is correct
