5 0

Answer:

Step-by-step explanation:

The angle 30° and 2x are complementary angles.

Two angles are called complementary angles, if their sum is one right angle (90°).

Therefore we have the equation:

30 + 2x = 90 <em>subtract 30 from both sides</em>

2x = 60 <em>divide both sides by 2</em>

x = 30
