To answer this question let us first define what a rational and irrational number is. A rational number is basically a number whose decimals are terminating (ie have an end) or repeating (continuously repeats the same pattern.
An example of this from your question would be
5.3 - terminating rational number
5.333333333333..... - repeating rational number
Irrational numbers are basically numbers whose decimals are non terminating and non repeating.
An example would be the square root of 29. When plugged in a calculator this would result in <span>5.3851648071.....
</span>This number goes on and on with no set pattern.
Student is wrong An exterior angle of a triangle can be adjacent to the right angle of a right triangle, so an exterior angle can be a right angle.
<h3>What is exterior angle?</h3>
The Exterior Angle is the angle between any side of a shape, and a line extended from the next side.
The student make an error he states that the exterior angle of a triangle can never be a right angle.
The correct answer will be option D that is An exterior angle of a triangle can be adjacent to the right angle of a right triangle, so an exterior angle can be a right angle.I have also attached the diagram of the triangle for better understanding.
