Answer: Option 'C' is correct.
Step-by-step explanation:
Since we have given that
∠1 = 62°
∠2 = 53°
∠3 = x°
As we know that "Sum of all angles in triangle is supplementary":
[tex]\angle 1+\angle 2+\angle 3=180^\cir\\\\62^\circ+53^\circ+x=180^\circ\\\\115^\circ+x=180^\circ\\\\x=180^\circ-115^\circ\\\\x=65^\circ[/tex]
Hence, Option 'C' is correct.
