MCQ
In fig, in $\triangle\text{ABC}, AB = AC$, then the value of $x$ is:
- A$100^{\circ}$
- B$80^{\circ}$
- C$120^{\circ}$
- ✓$130^{\circ}$
✓
Answer
Correct option: D.
$130^{\circ}$
Triangle $ABC$ is an iscosceles triangle and hence in the triangle other two angles are $50$ and $50.$
Therefore,$X = 180 - 50 = 130$
Therefore,$X = 180 - 50 = 130$
