Answer:
O {11, 17, 26}
Explanation:
Only {11, 17, 26} can represent the sides of a triangle.
One very important rule to take note of is that:
The value of any side of triangle is greater than the difference between any two sides and less than the sum of the two sides.
{11, 17, 26}
So;
lets assume the third side = y = 26
17 - 11 < y < 17 + 11
6 < y < 28
Since y is between 6 and 28, it satisfies the expression and it is true.

Answer:
Scientists use waves to study the different layers of the earth. Usually, they use seismic waves, which are waves generated by earthquakes or nuclear-test explosions. So, scientists study the path and speed of these waves through the earth to decipher boundaries and the materials that make up the layers.
