The very first step is to take LCM of the given expression

Perform arithmetic operations o the numerator

Divide the numerator and denominator by 2


The expression can't be further simplified;
Hence,
= 
Answer:
⇒
is the required relationship.
Step-by-step explanation:
Let us assume, the given right angled triangle is ΔPQR.
Here. PQ = Perpendicular of the triangle.
QR = Base of the triangle.
PR = Hypotenuse of the triangle.
Now, PYTHAGORAS THEOREM states:
In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides“
⇒
Hence in ΔPQR: 
And the above expression is the required relationship between the sides of a right triangle.
The chances are 1 out of 26. because there is only one 7 out of the 26 numbers.
