Answer: 26
============================================================
Step-by-step explanation:
The given complex number is in the form a+bi
a = -10
b = 24
The magnitude of the complex number is given by the formula
sqrt(a^2+b^2)
It's the distance from (0,0) to (a,b) on the xy plane.
So, that distance or magnitude is...
sqrt(a^2+b^2)
sqrt((-10)^2+24^2)
sqrt(100+576)
sqrt(676)
26 is the magnitude
