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