Answer:

Step-by-step explanation:

Use Pythagoras’s theorem

36^2 + 15^2 = xz^2

xz = 39

Answer:

39km

Step-by-step explanation:

In triangle XYZ, XY = 15km and YZ = 36km.

We need to find XZ.

So here Pythagoras theorem can be used, according to which

h² = b² + a²

h² = 36² + 15²

h² = 1296 + 225

h² = 1521

h = √1521

h = 39
