Question

If (y, 15, 17) is a Pythagorean triplet where y is its smallest member, find the value of y.​

Answer 1

Answer:

If (y, 15, 17) is a Pythagorean triplet where y is its smallest member, then using Pythagoras theorem:

${h}^{2} = {b}^{2} + {p}^{2} \\ {17}^{2} = {15}^{2} + {y}^{2} \\ 289 = 225 + {y}^{2} \\ 289 - 225 = {y}^{2} \\ 64 = {y}^{2} \\ \sqrt{64} = y \\ 8 = y$
