we know that
The conjugate of a complex number is the number with equal real part and imaginary part equal in magnitude but opposite in sign
so
In this problem we have

the conjugate is equal to--------> 
therefore
<u>the answer is the option</u>
10+3i
36; 351; 66; 1,017; 113,331; 1,968; 537; 417; 3,813
<span>P=34</span> inches<span>
a= left side=6 inches</span>
b= top side
P=2a+2b<span>
<span>P=34=2*6+2b
34=12+2b
b=11</span></span>
the length of the top side is 11 inches
