Answer» option d is the correct answer of the given question Checking out the possibilities of the third side will give the answer. xy = 4xy could be 2 *2 or 4 * 1221222 These are the possible triangles.223441 22x will be a triangle if x is 1, 2 or 3 (trial and error).44x is a triangle only if x is 1.1. 221 is acute. 12+ 22> 222. 222 is equilateral. So acute.3. 223 is obtuse. 22+ 22< 324. 144 is acute. 12+ 42> 42 The question is" x, y, z are integer that are side of an obtuse-angled triangle. If xy = 4, find z."And so, the third side has to be 3 Hence, the answer is 3. Choice B is the correct answer. B is the correct answer b is the correct answer |
