Ok so its a guessing game
I say its 40+10 because
40-10{one # is 10 less than)=30
10(3){three times the other number}=30
so 40+10=50
Answer:
its actaully c because its left alone once you subtract

Well since angle 1 and 2 are vertical angles 1=2 , 2=1 angle 3 is congruent to angle 2 which also equals 108* so if I'm not mistaking angle 3=108* also. HOPE THIS HELPS!!!!!! XD
