Question

The triangle is not necessarily drawn to scale, and the angles can vary. Create a compound inequality for the side length x using the Triangle Inequality.

A. 2 < x < 12
B. 5 < x < 7
C. 5 < x < 12
D. 2 < x < 7

Answer 1

A

Explanation:

given 2 sides of a triangle then the third side x is in the range

difference of 2 sides < x < sum of 2 sides , that is

7 - 5 < x < 7 + 5

2 < x < 12
