Answer:

Explanation:
Since the triangle is a right-angled triangle, we can use Pythagoras Theorem to solve for XZ.
In the triangle,
XZ = Hypotenuse
Base = XY = 12.7 cm
Perpendicular = YZ = 3.5 cm
Pythagoras Theorem:

Put the given data
(XZ)² = (12.7)² + (3.5)²
XZ² = 161.29 + 12.25
XZ² = 173.54
- Take square root on both sides
√XZ² = √173.54
XZ = 13.17 cm
