If it’s a triangle then it has to equal 180
so 48+54+x=180
48+54=102
180-102=x
x=78
Answer:

Step-by-step explanation:
Given number is
. We need to find the complex conjugate of the given number.
We will use the general rule to find out the complex conjugate of the number.
The complex conjugate of
will be 
And the complex conjugate of 
So, the complex conjugate of
is
