angle for triangle is 180°
angle ACB is 75° because it has mention that is an isosceles triangle
So that angle of BAC is 180°-75°-75°=30°
In order to find the product of two complex numbers their magnitudes are multiplied and their arguments(measure of angles) are added up.
For z₁
Magnitude = 4
Argument = π/3
For z₂
Magnitude = 3
Argument = 2π/5
So, the product of z₁ and z₂ will be:
