Answer:
The answer is option C
Step-by-step explanation:
Angles in a triangle add up to 180°
Since the above figure is a right angled triangle one of it's angles is 90°
To find the unknown angle add the known angle and 90° and subtract them from 180°
That's
? + 35 + 90 = 180
? + 125 = 180
? = 180 - 125
We have the final answer as
? = 55°
