a) use the cosine rule.
b) 110 because in a quadrilateral, an angle and an angle opposite of it both add up to 180, in this case 70 is there and 110 on the other side because they add up to 180.
c) u use the sine rule ( start with 70-37 )
d i) 70
  ii) too long cant really explain this question but now u know how to do the others :P
