Answer:

66°

Step-by-step explanation:

Complementary angles are those that add up to 90 degrees. Since a and b are complementary, we can write:

∠a + ∠b = 90

We already know that ∠a = 24°, so we can plug this in:

24 + ∠b = 90

∠b = 90 - 24 = 66°

Thus, the answer is 66°.

Which of the following inequalities represents the graph shown below on<br> the real number line?
pav-90 [236]

Answer:

-3 < x ≤ 1

Step-by-step explanation:

To our left, we have an unshaded circle at -3. This means that -3 is included in the possible value of x. And as such, we can say -3 < x.

To our right, we have a shaded circle at 1. This means 1 is included in the possible values of x. And as such, we can say x ≤ 1.

Thus, we can represent the two statements as one, thus:

-3 < x ≤ 1
