Question

I need help with #2

Answer 1

28 < x < 114

Explanation:

• x cannot be larger than or even equal to 71 + 43 = 114. So it must be less than 114.
• But there are limits on the other end as well. 43 +x > 71, otherwise you won't have a triangle. so you have to solve that inequality as well
• 43 + x > 71 Subtract 43 from both sides.
• 43-43 + x > 71 - 43
• x > 28
• To put this in the form of the answer you need it looks like this.
• 28 < x < 114
