Question

In the following figure, AOB is a line. Then x=…….​

Answer 1

Answer:

The answer will be 45°.

Step-by-step explanation:

Since, AOB is line.

Thus,  ∠AOC and ∠BOC are forming linear pair.

Hence, ∠AOC + ∠BOC = 180

45 + ∠BOC = 180

 ∠BOC = 135°.

Now, it's given that;

∠BOC = 3x;

Thus, 3x = 135

x = 45°.

That's all.
