Question

If 6, 8 and c form a Pythagorean triplet with 6 being the smallest number then find the value of c.

• A. 4
• B. 5
• C. 7
• D. 10

Answer 1

The correct option is D

10

For a set of natural numbers to be a Pythagorean triplet, the sum of the squares of the 2 numbers should be equal to the square of the third number.

$6^2+8^2=c^2$

$36+64=c^2$

$c^2=100$

$\Rightarrow c=\sqrt{100}=10$
