Answer:

6, 7, 9 are solutions
2 is not

Step-by-step explanation:

Divide the inequality by 3 to see what the solutions are:

6 ≤ y

Now, you can tell that 2 is not a solution, but 6, 7, and 9 are solutions. The latter values are all at least 6.

IrinaK [193]

Answer:

The angles are 110, 110 and 140

Step-by-step explanation:

Let the equal angles be x.

So we have angles x, x and another third one

Now, the other third angle is 30 degrees larger than x, this means that the other third angle is 30 + x

Since they are angles at a point, adding the three together will make or give 360.

Thus,

x + x + x + 30 = 360

3x + 30 = 360

3x = 360-30

3x = 330

x = 330/3

x = 110

So the other third angle is 110 + 30 = 140

So the angles are 110, 110 and 140
