In triangle ABC , angle A measures 50 degrees, angle B measure      (2 x+40) degrees and angle Z measures (4 x +8) degrees.Since triangle ABC congruent to triangle XYZ . Therefore angle C will equal to angle Z . So

angle Z=angle C= 4x+8

By angle sum property of triangle.

`/_A+/_B+/_C=180^0`

50+(2x+40)+(4x+8)=180

6x+98=180

6x=180-98

6x=82

x=82/6

Thus   answer is `x=(82/6)^0=(41/3)^0`
