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)
