Detailed Solution

Here, we have to find the number of degrees at four right angles.
We know that a right angle looks like 3 o’clock on the watch and so the angle formed between two lines is called an angle.
Here, the angle is a right angle having a degree equal to 90 ° .  
But here, we need four right angles.
Thus, four right angles =4× 90 ° = 360 ° .  
Hence, the degrees in four right angles are 360 ° .  
Thus, option (4) is correct.
