To find the value of z, we need to subtract the sum of angles x and y from 180 degrees (since the sum of the angles in a triangle is always 180 degrees).
z = 180 - (x + y)
From the diagram, we can see that x = 120 degrees and y = 45 degrees.
Therefore, z = 180 - (120 + 45) = 180 - 165 = 15 degrees.
So, the value of z is 15.
The correct answer is option D) 15.
