MCQ
Find the value of $x$ in given figure.
- A$120^\circ$
- B$50^\circ$
- ✓$60^\circ$
- D$180^\circ$
✓
Answer
Correct option: C.
$60^\circ$
The exterior angle $(120^\circ )$ is equal to the sum of the two opposite interior angles $(60^\circ + x)$
Thus, $120^\circ = 60^\circ + x$
$x = 60^\circ $
Thus, $120^\circ = 60^\circ + x$
$x = 60^\circ $
