Answer 1

The value of x in the right triangle using the Pythagorean theorem is 15 units

How to determine the value of x in the right triangle?

From the right triangle (see attachment), we have the following Pythagoras theorem

x² = 12² + 9²

Evaluate the exponents

x^2 = 144 + 81

Evaluate the sum

x^2= 225

Take the square root of both sides

x = ±15

The value of x cannot be negative.

So, we have:

x = 15

Hence, the value of x is 15 units
