Conjugate of (a - bi) is (a + bi).
Just change the sign on the imaginary part.

Answer:
sqrt(170) or approximately 13.038
Step-by-step explanation:
We can use the Pythagorean theorem to find the diagonal since the diagonal makes a right triangle
a^2 + b^2 = c^2
We need to find the leg lengths
ML = 7 and MJ = 11
7^2 + 11^2 = JL^2
49+ 121 = JL ^2
170 = JL ^2
Take the square root of each side
sqrt(170) = JL
13.038 = JL
Answer:
(5sqrt(2), 45 deg)
(-5sqrt(2), 225 deg)
Step-by-step explanation:
(x,y)=(5,5)
So theta=arctan(5/5)=arctan(1)=45 degrees
Now r! r=sqrt(x^2+y^2)=sqrt(5^2+5^2)=sqrt(50)=sqrt(25)sqrt(2)=5sqrt(2)
So one polar point is (5sqrt(2) , 45 degrees)
Now if we do 180+45=225 degrees... this puts us in the 3rd quadrant... to get back to quadrant 1 we just take the opposite of our r
so another point is (-5sqrt(2) , 225 degrees)
