+642 
so for the first one, I got this
D + B = 180 and A + C = 180
since A+C=180 and we know what C is, 74 then A + 74 = 180 am i correct?
for the second one, i got 77 degrees is this right?
the answer i got for this one is 180 but i feel like im wrong
I got 62 is this correct
this one is actually a bit hard wasn't able to solve it
