The magnitude of a complex number is defined in the complex space where the real numbers are on the horizontal axis, and the complex (imaginary) part is on the vertical axis.

The magnitude is defined to be the distance of the given point to the origin, namely for a complex number

a+bi,

|a+bi|= √(a²+b²)

So

|8+15i|=√(8²+15²)=17
