AB = CB
Because they are congruent
Therefore CB = 5.9
Given perimeter = 17
CB+BE+ED+DC = 17
5.9 + BE + 2.8 + 5.6 = 17
BE + 14.3 = 17
BE = 17 - 14.3
= 2.7
Hope I helped
If I did please give brainlest answer
Thanks
12.3 or 12 3/10
4.5 + 7.8 = 12.3
or
4 10/20 + 7 16/20 = 11 26/20
11 26/20 can be simplified to 12 6/20 and further simplified to 12 3/10
