Answer:

$z_1 = \sqrt{84.5} - i \, sin(\sqrt{84.5})$

Step-by-step explanation:

$z_1$ has the following properties:

$|z_1| = 13$

$\theta = 315$ º = 1.75 π (π = 180º)

therefore, z₁ = 13 * [ cos(1.75 π) + i sin(1.75 π) ] = 13*[cos(1.75π - 2π) + i sin(1.75π - 2π)] = 13*[cos(-π/4) + i sin(-π/4)] {this is due to periodicity} = 13*(√2/2 - i √2/2) = $\sqrt{84.5} - i \, sin(\sqrt{84.5})$
