• what if we get the answer that the sum of angles of two sides is no greater than the third side
• there is a mistake in the solution of question 45. If 3 and 8 are the lengths of two sides a triangle, the length of the third side can be neither 11 nor 5, thus the answer should be 8 (only II).

• #45 ans is A. the law states that the sum of two sides of a triangle cannot equal to the length of another side and by that logic if you plug in 5 there your triangle will be incomplete because 3+5=8.
