The measures of two sides of a triangle are 5.2 and 8.1. Determine the range of values for the third side of the triangle.(1 point
The third side of a triangle must be less than the sum of the other two sides and greater than the difference between the other two sides.
So the third side must be greater than |5.2 - 8.1| = 2.9 and less than 5.2 + 8.1 = 13.3.
Therefore, the range of values for the third side of the triangle is 2.9 < third side < 13.3.
