Question

The legs of a right triangle are 5 units and 15 units. What is the length of the hypotenuse?

Answer 1

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

$x=\pm\sqrt{250}$

Length cannot be negative.

So, Length of the hypotenuse is √250 units.

Therefore, Option C is correct.

Answer 2

To find the answer you have to use pythagorean theorem;

a² + b² = c²          where a and b are the legs and c is the hypotenuse.

5² + 15² = c²

25 + 225 = c²

250 = c²

√250 = √c²

√250 = c
