2 answers:
The top corner is 180-78=102°
Sum of the corners should be 180°, so
39+102+5z+4=180 => 5z = 180-145 => z=35/5=7°
my previous answer of 29 was indeed wrong!!!
sorry for that!!
Straight angle = 180
so 180 - 78 = 102
sum of interior angles in a triangle = 180
102 + 39 + 5z + 4 = 180
5z + 145 = 180
5z = 35
z = 7
answer
x = 7
