x=5

Step-by-step explanation:

Plugin the number into sthe pythagroyean theorm (a²+b²=c²), with 3 replacing a, 4 replacing b, and x replacing c.

3²+4² = x²

9+16 = x²

25 = x²

√25 = √x²

x = 5

It's helpful to remember that if the opposite and adjacent sides of the triangle (in this case CB and AB) are the lengths 3 and 4, the hypotenuse (longest side of the triangle) is always equal to 5.
