Answer:
Therefore the value of EC is 13 unit.
Step-by-step explanation:
Given:
ABCD is a Rectangle
EC = 6x + 1
AE = x +11
To Find:
EC = ?
Solution:
ABCD is a Rectangle .........Given
Diagonal of Rectangle Bisect each other. .......Property of Rectangle
[tex]AE = EC[/tex]
Substituting the values we get'
[tex]x+11=6x+1\\6x-x=11-1\\5x=10\\x=\dfrac{10}{2}\\\\x=2[/tex]
Substituting 'x' in EC we get
[tex]EC=6\times 2+1=13\\EC=13\ unit[/tex]
Therefore the value of EC is 13 unit.
