Angles and Lines

Forgive us for being obtuse, but this is a cute concept, and we think it’s right for you.

Complementary and Supplementary Angles

Given that $$\color{green}{\text{(green angle)} = 31^\circ},$$ which of the following is complementary to that $$\color{green}{\text{green angle}}$$?

Which pair of angles are supplementary?

Suppose $$\angle A = 65^\circ$$, $$\angle B\,$$ is complementary to $$\angle A,$$ and $$\angle C$$ is supplementary to $$\angle B.$$ What is the measure of $$\angle C ?$$

If $$\angle A=5 ^\circ$$ and $$\angle B$$ is the supplement of $$\angle A,$$ then $$\angle A + \angle B$$ forms a(n) $$\text{__________}.$$

$$\quad \text{A)}$$ acute angle
$$\quad \text{B)}$$ right angle
$$\quad \text{C)}$$ obtuse angle
$$\quad \text{D)}$$ straight line
$$\quad \text{E)}$$ none of the above

Find the measure of $$\angle Z.$$
