Answer 1

$\\ \sf\longmapsto ZY^2=XY^2-XZ^2$

$\\ \sf\longmapsto ZY^2=10.2^2-5.9^2$

$\\ \sf\longmapsto ZY^2=104.04-34.81$

$\\ \sf\longmapsto ZY^2=69.23$

$\\ \sf\longmapsto ZY=\sqrt{69.23}$

$\\ \sf\longmapsto ZY=8.3cm$

Answer 2

Step-by-step explanation:

the distance from Z to Y =

√10.2² - 5.9²

=√104.04 - 34.81

=√ 69.23

= 8.3 cm
