The length of the unknown side in the adjacent triangle is
The answer is: 12 سم
The length of the missing side in the adjacent triangle is 12 cm.
This is determined by the Pythagorean theorem, which states that the square of the longest side of a right triangle (the hypotenuse) is equal to the sum of the squares of the other two sides.
In this case, the missing side is equal to the square root of (4 ^ 2 + 3 ^ 2) = 12 cm.
