Question

XYZ is a triangle,right angled at x .IfXZ is 3 CM,XY is 4 cm.Find XY.Send it soon guys​

Answer 1

Answer:

5

Step-by-step explanation:

xy=3cm and yz=4cm

by pythagoras theorem, xy^2 + yz^2 = xz^2

i.e. 3^2 + 4^2 = xz^2

9 + 16 = xz^2

25 = xz^2

5=xz

Answer 2

Question:-

XYZ is a triangle,right angled at x .IfXZ is 3 CM,XY is 4 cm. Find YZ.

$\huge\mathcal\blue{Answer}$

Given:-

• XY = 4cm
• ZX = 3cm

To find:-

• ZY = ?

_________________

➭ We know it is a right angle triangle and for right angled triangle Pythagoras property is used to find third side.

$➦ {a^2} ={ b^2} + { c^2} \: (pythagoras \: theorem)$

• Here a = ZY
• b = XY = 4cm
• c = ZX = 3cm

-------------------------

$➳ \: { a^2} = { 4^2} \: + { 3^2}$

$➳ \: a = \sqrt{16 + 9}$

$➳ \: a = \sqrt{25} = 5cm$

___________________

➭ So the value of ZY is 5cm.
