The perimeter of a scalene triangle is 14.5 cm. the longest side is twice that of the shortest side. which equation can be used to find the side lengths if the longest side measures 6.2 cm?
choose the correct answer.
6.2 + b = 14.5
9.3 + b = 14.5
12.4 + b = 14.5
18.6 + b = 14.5

6.2/2 = 3.1 shortest side

6.2 +3.1 = 9.3 shortest and longest added together

 still have a missing side (b)

 so 9.3 +b = 14.5 is correct

answer: answer is b.

[m < b = 120º]

step-by-step explanation:

could u provide us some answer choices or hmm idk maybe a table for us to anser with ? ?
