MCQ
In the given figure, the measure of $\angle\text{a}$ is:
- A$150^\circ$
- ✓$30^\circ$
- C$15^\circ$
- D$50^\circ$
✓
Answer
Correct option: B.
$30^\circ$
In the given figure
$150^\circ\angle\text{a}=180^\circ$ (linear - pair)
$\angle\text{a}=180^\circ=150^\circ$
Therefore,
$\angle\text{a}=30^\circ$
$150^\circ\angle\text{a}=180^\circ$ (linear - pair)
$\angle\text{a}=180^\circ=150^\circ$
Therefore,
$\angle\text{a}=30^\circ$
