Answer 1

Answer:

for 20 number.

<AEB=142

<BEC=38

<DEC=142

<AED=38

Step-by-step explanation:

or, m<AEB+m<BEC=180(Straight line)

or, 6x-32+2x-20=180

or, 8x-52=180

or, x=29

replacing value of x

m<AEB=6×-32

=6*29-32

=142

m<BEC=2X-20

=2*28-20

=38

m<AED=m<BEC=38(Vertcally opposite angle)

m<DEC=m<AEB=142(Vertically opposite angle)
