Question

is 28,21 and 35 a pythagorean triplet​

Answer 1

Concept:

A, B, and C are the three positive integers, and the Pythagorean triples are written as a2+b2 = c2. The symbols for these triples are (a,b,c). Here, a represents the right-angled triangle's hypotenuse, b its base, and c its perpendicular.

To find:

The Pythagorean triplet of 28, 21, and 35.

Solution:

We know that a Pythagorean triplet is the sum of the square of hypotenuse and base and is equal to the square of perpendicular of a right-angled triangle.

So, we know that the square of 21 = 441

28 = 784

35 = 1225

So, to check whether it's a Pythagorean triplet or not, we will add the squares of 21 and 28, and the result should be equal to the square of 35, that is, 1225.

441+784=1225

∴21, 28, and 31 is a Pythagorean triplet.
