MCQ
If $\angle\text{A}$ and $\angle\text{B}$ are two adjacent angles of a parallelogram. If $\angle\text{A}=70^\circ,$, then $\angle\text{B}=$?
- ✓$110^\circ$
- B$180^\circ$
- C$70^\circ$
- D$90^\circ$
The adjacent angles of parallelogram are supplementary.
$\angle\text{B}+ \angle\text{B}=180^\circ$
$70^\circ+\angle\text{B}=180^\circ$
$\angle\text{B}=180^\circ-70^\circ=110^\circ$
