Answer:

1)For angle efd yo can do (b plus 35 egicaltu 90)then value of b will came then you can do b plus 35 plus e egicaltu 180 (straight angle) then by calculating value of efd can easily calculated.

2)for ehf:30 plus c egicaltu 180(being straight angle).

3)for hfg:35 plus b egicaltu 90 .then value of b can be calculated.

4)for angle g: value of b plus 30 plus a egicaltu 180(sum of angle of triangle as reasion)

5)for angle e:value of c plus 35 plus d egicaltu 180 (being sum of angle of triangle).
