Question

answer this please, I need it urgently​

Answer 1

Answer:

11.18 cm

Step-by-step explanation:

In ∆ABE,

By Pythagoras theorem,

EB^2 = 8^2 + 6^2

EB^2 = 64 + 36

EB^2 = 100

EB = √100

EB = 10 cm

In ∆DBC,

By Pythagoras theorem,

DB^2 = 4^2 + 3^2

DB^2 = 16 + 9

DB^2 = 25

DB = √25

DB = 5 cm

In ∆EBD,

By Pythagoras theorem,

ED^2 = 10^2 + 5^2

ED^2 = 100 + 25

ED^2 = 125

ED = √125

ED = 5√5

ED = 5 x 2.236

ED = 11.18 cm
