Answer:
y = 21°, x = 118°
Explanation:
Firstly, since it is a parallelogram, we know that △ACD ≅ △ABC. This means that y = 21°. It's been too long since I have done geometry so I do not remember the exact rule, but I'm sure it's something like the bisection of angles for parallelogram diagonals etc.
We also know that all the angles of a triangle must add up to 180°, so:
41° + 21° + x = 180°
x = 180° - 41° - 21°
x = 118°
