Question

13 square =PQ square +12 square

Answer 1

I think the following is some sort of pythagorean triplet asking The value of PQ.

Let PQR be a right angled triangle.
According to the pythagorean theorem, we know that — Hypotenuse square = base square + altitude square.
Now, we know that the hypotenuse is the largest side of a triangle. So the side with 13 units is the hypotenuse and named as PR & side with 12 units be RQ
By P.T,
PR² = PQ² + RQ²
→13² = PQ² + 12²
→PQ² = 13² - 12²
→PQ² = 169 - 144
→PQ² = 25
→PQ = √25 = 5

Therefore, the value of PQ is 5
