Given:

The right angle triangle with legs 4 units and 7 units.

To find:

The length of hypotenuse.

Solution:

Pythagoras theorem: In a right angle triangle,

[tex]Hypotenuse^2=Base^2+Perpendicular^2[/tex]

Let x be the length of the hypotenuse.

Using the Pythagoras theorem for the given triangle, we get

[tex]x^2=4^2+7^2[/tex]

[tex]x^2=16+49[/tex]

[tex]x^2=65[/tex]

Taking square root on both sides, we get

[tex]x=\sqrt{65}[/tex]                [∵Side length cannot be  negative]

[tex]x\approx 8.06[/tex]

Therefore, the length of the missing side for the given right angle triangle is 8.06 units.
