Which of the following is the conjugate of a complex number with 5 as the real part and −2 as the imaginary part?

a. 5 + 2i
b. −5 − 2i
c. −5 + 2i
d. 5 − 2i

Hello!

Given two real numbers "a" and "b", the complex number z is defined as:

The complex conjugate of "Z = a + bi" is "Z = a – bi"

Given the complex number , "a" is called the real part and "b" the imaginary part.

Therefore:

Re(a) = 5

Im(b) = -2

a. 5 + 2i

180°

step-by-step explanation:

sum of equilateral triangle=180°

< n=60°

< m=120°°[angle supplementary of equilateral angle]

< m+< r+< x=360°(sum of exterior angle of triangle)
