Answer:
-10/3 is the answer
Step-by-step explanation:
Given are two complex numbers as

Recall Demoivre theorem as
(cosA+isinA)(cos A+isin B) = cos(A+B)+isin(A+B)
Hence here we have sum of angles  as
A+B = 63+117 =180

=
Since sin180=0 and cos 180=-1
 
        
             
        
        
        
The angle of YWZ is equal to the angle of YWX, and angle WYX is also a right angle due to the congruency of segments WZ and WX.
Every triangle has an angle total of 180 degrees, so angle WXY is equal to
180 - (WYX + YWX)
180 - (90 + 17)
73
Angle WXY has an angle value of 73 degrees.
