Question

Triangle XYZ is a right-angled at Y. If XY = 5cm and YZ = 12cm. Find the
length of XZ.

Answer 1

Answer:

the length of xz is 7

Step-by-step explanation:

xy+yz

5+12

12-5=7

Answer 2

Answer:

13cm

Step-by-step explanation:

XY=5cm

YZ=12cm

∠Y =90°

Let the length of XZ be x

Using Pythagoras theorem,

(5)² + (12)² = x²

25 +144 =x²

169= x²

∴ x = √169

⇒13cm

∴XZ is 13cm
