I dont know how to find a .
1 answer:
To find a,construct a line that parallel to AB and DE cutting c, which you could refer to the photo((sorry for my terrible diagram ^^;;
from the photo,we can see that
a= <BCG + <GCE
<BCG=44° (alt.<, AB//FG)
<GCE=20° (alt<, FG//DE)
thus,a= 44°+20° =64°
hope it helps!

The correct answer is A. 10
8 divided by 0.8 = 10
10x0.8=8
Sinx=1/2
sin30=1/2
therefore x=30 degree
