What is the value of x?

Answer:
Value of x is 39.
Step-by-step explanation:
In the given figure, we are given a right angled triangle with one side of 15 units, other is of 36 units. We have to find the third side of the triangle.
By Pythagoras theorem:
The square of side opposite to the right angle of the triangle is equal to sums of square of other two sides. It can be written as:
[tex](Hypotenuse)^2 = (Side1)^2 + (Side2)^2[/tex]
[tex]Hypotenuse = \sqrt{(Side1)^2 + (Side2)^2}[/tex]
Now, applying the Pythagoras theorem to the given right angled triangle we have,
[tex]x^2 = (15)^2 + (36)^2\\x = \sqrt{1521} }\\x = 39[/tex]
Hence, value of x is 39.
