Answer 1

The Length of third side is 52 units.

Explanation:

Given:

Length of First side = 48

Length of second side = 20

Also given the angle between them is 90°.

Hence we can say figure shown is a right angled triangle.

For finding the third side we can use Pythagoras theorem which states that;

"If a triangle is right angled then, the Square of the hypotenuse is equal to sum of the square of the other two sides."

`Third \ side ^2=First \ side^2+Second \ side^2`

Hence substituting the values we get;

`Third\ side^2= 48^2+20^2 = 2304+400 =2704`

Now taking Square root on both side we get;

`√(Third \ side^2) = √(2704)\\ Third \ side = 52 \ units`

Hence Length of Third side is 52 units.
