I guess you have a parallelogram. If so than m%E2%88%A0A+=m%E2%88%A0C and m%E2%88%A0B+=m%E2%88%A0D

given:
m ∠ A+=+%282x+%2B+4%29°
and
m ∠ B+=+%283x+-34%29°.

then
m+∠ A+=+180- m ∠ B+
2x+%2B+4=180-%283x+-34%29
5x+=+210+
x=42

then
m∠A+=+%282%2A42+%2B+4%29+=88°=>m∠C=88°
m∠B+=+%283%2A42+-34%29=92°=>m∠D=92°
