You add/subtract complex numbers simply by adding/subtracting real parts and imaginary parts.
So, the real part of this sum is the sum of the real parts:
And the imaginary part of this sum is the sum of the imaginary parts:
So, you have
Answer:
Step-by-step explanation:
By applying Pythagoras theorem in the triangle given in the picture,
(Hypotenuse)² = (leg 1)² + (leg 2)²
PO² = (15)² + 8²
PO² = 225 + 64
PO = √289
PO = 17
By applying sine rule in the given triangle,
sin(x°) =
=
cos(y°) =
Relation between the ratio of sin(x) and cos(x) will be,
=
=
