If x, y, and z are the lengths of the three sides of a triangle, is y > 4?
(1) z = x + 4
(2) x = 3 and z = 7
(1) z = x + 4
(2) x = 3 and z = 7
Here we use the property of triangle that sum of any 2 sides has to be greater than the third side.
Statement 1 Three sides of triangle are x, y, x+4
Since sum of any 2 sides has to be greater than third side,
\(x+y>x+4\)
y>4. Hence, Statement 1 is SUFFICIENT
Statement 2 Sides of triangle are 3, y, 7
\(3+y>7\)
y>4. Hence Statement 2 is SUFFICIENT
Hence Answer is D
