Answer:

248°

Step-by-step explanation:

y = 180°- 56°

  = 124°

x = 124° because opposite angles of a parallelogram are equal

x + y = 124° + 124°

        = 248°

Answer:

x + y = 248

Step-by-step explanation:

Using the property : Sum of co- interior angles = 180

[tex]\angle y + 56 = 180\\\\\angle y = 180 - 56 = 124\\\\\angle x + 56 = 180\\\\\anle x = 180 - 56 = 124\\\\\angle x + \angle y = 124 + 124 = 248^\circ[/tex]
