Answers
Number of possible triangles with any three of the lengths 1.2cm 4.2cm 5.9cm and 8.1cm is 1 (One)
Step-by-step explanation:
the number of possible triangles with any three of the lengths 1.2cm 4.2cm 5.9cm and 8.1cm
A triangle has three Sides
3 Sides out of 4 can be selected in ⁴C₃ = 4 Ways
ans Combination must satisfy that sum of two sides > third side
Possible Combination
1.2 4.2 5.9 1.2 + 4.2 < 5.9 (Triangle not possible)
1.2 4.2 8.1 1.2 + 4.2 < 8.1 (Triangle not possible)
1.2 5.9 8.1 1.2 + 5.9 < 8.1 (Triangle not possible)
4.2 5.9 8.1 only Possible Triangle
only one triangle possible
Number of possible triangles with any three of the lengths 1.2cm 4.2cm 5.9cm and 8.1cm is 1 (One)
