Answer:
BD=7
ED=5
BE=7
AD=10
AE=5
Explanation:
given CD = 7 you use that to find BD and BE because CD´s line length is the same as BD and BE
given BC = 5 you use that to find ED and AE and AD because BC is the same length as ED (they create the same triangle) and than given AE also equals 5 you add ED and AE to get AD
hope this helps
