The diagram shows three aid stations in a national park. Choose the values of x, y, and z that COULD represent the distances between the stations.

Ax = 7 miles, y = 8 miles, z = 18 miles
Bx = 4 miles, y = 7 miles, z = 12 miles
Cx = 5 miles, y = 9 miles, z = 14 miles
Dx = 8 miles, y = 12 miles, z = 15 miles

All possible triangles must obey the rule that the sum of any two sides must be greater than the third side...

Only D. is a possible combination of sides

Answer:

The correct option is D.

Step-by-step explanation:

The diagram shows three aid stations in a national park.

From the given graph it is clear that the three aid stations forms a triangle.

According to the properties of triangle the sum of two smaller sides is more than the larger side.

In option A, the given sides are x = 7 miles, y = 8 miles, z = 18 miles.

\(7+8=15<18\)

Therefore the option A is incorrect.

In option B, the given sides are x = 4 miles, y = 7 miles, z = 12 miles.

\(4+7=11<12\)

Therefore the option B is incorrect.

In option C, the given sides are x = 5 miles, y = 9 miles, z = 14 miles.

\(5+9=14\)

Therefore the option C is incorrect.

In option D, the given sides are x = 8 miles, y = 12 miles, z = 15 miles.

\(8+12=20>15\)

Here the sum of two smaller sides is more than the larger side. Therefore the option D is correct.
