Question

xyz is a triangle right angled at y and xz=25cm,yz=7cm,then xy is​

Answer 1

Answer:

24 cm

Step-by-step explanation:

apply pythagoras theorem  we get

25 square =7 square * side two square

side two square =625 -49

                           =576

side two = 24

Answer 2

Answer:

The length of side XY in ΔXYZ right angled at Y is 24cm.

Step-by-step explanation:

According to Pythagoras Theorem,

⇒$Hypotenuse^{2}= Perpendicular side^{2} + Adjacent side^{2}$

In ΔXYZ,

Hypotenuse, XZ= 25cm

Adjacent side,  YZ= 7cm

∴

Perpendicular side = $\sqrt{Hypotenuse^{2}-Adjacent side^{2} }$

=$\sqrt{25^{2}-7^{2}$

=$\sqrt{625-49}$

=$\sqrt{576}$

=24 cm

∴ Perpendicular side, XY= 24cm

The correct answer is XY=24cm.
