The diagram where angles 1 and 2 form a linear pair is D. A horizontal line has 1 line extending from it. Angles 1 and 2 are formed.
<h3>What is a linear pair?</h3>
It should be noted that a linear pair simply means angles that are formed when two lines intersect each other at a single point.
In this case, when a horizontal line has 1 line extending from it. Angles 1 and 2 are formed. This depicts a linear pair 
In conclusion, the correct option is D.

Answer:
Option C.
Step-by-step explanation:
Given information: The hypotenuse of a 45°-45°-90° triangle measures 22√2 units.
Let x be the length of one leg.
From the given figure it is clear that length of both legs are same.
According to the Pythagoras theorem, in a right angled triangle

Substitute  in the above formula.
 in the above formula.



Divide both sides by 2.

Taking square root on both sides.

The length of one leg is 22 units.
Therefore, the correct option is C.
 
        
                    
             
        
        
        
with the exception of perfect squares, all square root of whole numbers are irrational, e.g. √5
how about this one:
2.34334333433334.... I am increasing the number of 3s each time, thus
creating a decimal which never ends and never repeats.
or
12.3456789101112131415.... can you see what I am doing?
will it ever end? will it ever repeat?
