How many degrees are in a right angle?

The correct answer is: 90

A right angle is defined as an angle that measures exactly 90 degrees. This measurement is fundamental in geometry and serves as a benchmark for other types of angles. For instance, an angle less than 90 degrees is known as an acute angle, while an angle greater than 90 degrees but less than 180 degrees is called an obtuse angle. The specific measurement of 90 degrees in a right angle is critical in various applications, including construction, architecture, and engineering, where precise angles are necessary for the integrity and functionality of structures. The other options provided do not represent a right angle; 45 degrees is an acute angle, 180 degrees corresponds to a straight angle, and 30 degrees is also an acute angle. Thus, the only valid representation of a right angle is 90 degrees.
