if two triangles are similar then they are congruent
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
16
divide 12 by 3 since its 3/4 of the whole thing so 1/4=4
Town A starts with 2in and has a rate of accumulation of 6in every 1 hour
Town B starts with 9in and has a rate of accumulation of 3in every 1 hour
If X is number of hours then:
2+ 6X= 9+3X
6x-3x=9-2
3x=7
X=7/3 is about 2 hours
Set ? as x, and cross-multiply.
so x^2= 36
x = 6 or x = -6
