Answer: D. 10

Explanation:

As a basic concept, we are aware that the angle created on a straight line is equal to 180°.

One angle measures 30 degrees while the other measures 15x degrees.

To ensure that the angles add up to 180°, it is necessary to include both angles.

∴ 30° + 15x° = 180°

15x° = 180°- 30°

15x° = 150°

x° = 150°/15

∴ x° = 10

Proof: 30°+ 15×10° = 180°

30° + 150° = 180°

180° = 180°

The answer is D because the angle as a total is 180.

180-30=150

150/15=10

Therefore the answer is D/10.
