So we can write is also as:
k=2y+x
y=(k-x)/2
x=k-2y
k= 2[(k-x)/2] + (k-2y)
-16 is it. Have a good c o r o n a my man
So you know that the sum of angles in a triangle is 180°.
You know two of the angles in triangle WXZ. The two angles are angle WXZ, which is 50° and angle XWZ, which is 90°.
Now you can calculate angle WZX, by:
180-50-90=40°.
