Answer:
Option C is correct.
Step-by-step explanation:
Given:
Legs of the right angled triangle are 5 units and 15 units.
To find: Length of the Hypotenuse of the triangle.
Let x be the length of the hypotenuse.
using Pythagoras theorem,
x² = 5² + 15²
x² = 25 + 225
x² = 250
[tex]x=\pm\sqrt{250}[/tex]
Length cannot be negative.
So, Length of the hypotenuse is √250 units.
Therefore, Option C is correct.
