Question

please answer the 16th question.

Answer 1

1,3 and 5 is right in these options

Answer 2

16. Before answering, I must tell you that sum of the angles of a triangle=180 degrees
1. 3*45 degrees=135 degrees so triangle so not exist.
2. 2*90 degrees=180 degrees but one angle is left which cant be zero so triangle do not exist.
3. 3*60 degrees=180 degrees so triangle will exist.
4. two of the angles cant be obtuse since smallest obtuse integral angles are 91 and 2*91=182 degrees so triangle do not exist.
5. Sum of two acute angles is less than 180 so triangle will exist.
