Question

In a xyz, Xy = 4cm. yz= 3cm and y=90°, find XZ
using pythogrus theorems-​

Answer 1

The answer is that

√7 is correct

Answer 2

Answer:

angle Y is 90°. So the hypotenuse side will be XZ

using Pythagoras theorem:

XZ² = XY² + YZ²

XZ² = (4)² + (3)²

XZ² = 16 + 9

XZ² = 25

XZ = √25

XZ = 5cm
