Question

XYZ is a triangle, right angled at Z. If XY = 17 cm and XZ =15 CM, find YZ.​

Answer 1

Answer:

XYZ is a triangle, right angled at Z. If XY = 17 cm and XZ =15

then,

$YZ = \sqrt{ {XY}^{2} - {XZ}^{2} } \\ YZ = \sqrt{ {17}^{2} - {15}^{2} } \\ YZ = \sqrt{289 - 225} \\ YZ = \sqrt{64} = 8 \: cm$
