z_1=10+6 i, z_2=4+6 i

and

z

is a complex number such that

\operatorname{amp}\left(\frac{z-z_1}{z-z_2}\right)=\frac{\pi}{4}

, then the value of

|z-7-9 i|

is equal to

View answer and explanation

Correct option: A

3 \sqrt{2} \text{}

Option A (

3 \sqrt{2} \text{}

) is correct because it represents the magnitude of the complex number |z - 7 - 9i| after simplifying the given amplitude condition.
