Answer 1

Answer:

$\huge\red{Answer}$

Let

A,

B and

C be 3x, 2x and x respectively.

3x +2x +x = 180o (angle sum of

)

6x = 180o

x = 30

A = 90o,

B = 60o and

ACB =30o

Now,

ACB +

ACE +

ECD = 180o (angles on a straight line)

30o + 90o +

ECD = 180o

ECD = 180o – 120o = 60o

Hence,

ECD = 60o
