D{-10;-24},|d|=

To find the magnitude (or absolute value) of a complex number, you can use the Pythagorean theorem. The magnitude of a complex number is the square root of the sum of the squares of its real and imaginary parts.

In this case, the complex number is d = -10 - 24i.

The real part of d is -10 and the imaginary part is -24.

So, the magnitude of d, denoted by |d|, can be calculated as follows:

|d| = √((-10)^2 + (-24)^2)

|d| = √(100 + 576)

|d| = √676

|d| = 26

Therefore, the magnitude of the complex number d is |d| = 26.
