Answer 1

I'm skeptical of the correctness of your answer. How did you get it?

Answer 2

care to explain why?

If 10 is 60 and 12 is 40, 11 must be 180-(60+40) = 80

That means 14 must also be 80. If 10 is 60 and 14 is 80, 9 must be 40.

Because GN and FH are parallel, 6 must be the same as 10, and 7 must be the same as 11+12, so we have 6 = 60 and 7 = 120. 8 must the same as 6, so it is 60. And finally 3+8+9 must equal 180, so 3 + 60 + 40 = 180 --> 3 must equal 80, not 60.
