The answer is C.

Step-by-step explanation:

Answer:

C. 60º


Step-by-step explanation:

A triangle is called a right triangle when one of it's angle measures 90°.

We have been given the second angle as 30°.

The angles in a triangle add up to 180°.

∴ leting the third angle to be X;

X + 30° + 90° = 180°

X + 120° = 180°

X = 180° - 120°

   = 60°
