1. yes 


2. no ( sum of the angles in a triangle = 180 degrees . so, 105 + 90 already gives you 195 )


3. no ( sum of the angles in a triangle equals 180 degrees...so 75 +30 gives you 105 degrees..put if you compare the angle and the perimeter there is no possibility of getting 12.5 cm as your perimeter )
