MCQ
Find the value of $x$ in the adjoining figure.
- A$50^\circ$
- ✓$120^\circ$
- C$60^\circ$
- D$70^\circ$
✓
Answer
Correct option: B.
$120^\circ$
As, the sum of all angles of triangle is $180,$ the third angle $($adjacent to $x)$ would be $(180 - 50 - 70) = 60.$
Also, angles in straight line add to $180$ degrees. Thus $x$ would be $(180 - 60) = 120$ degree
Also, angles in straight line add to $180$ degrees. Thus $x$ would be $(180 - 60) = 120$ degree
