Question

in the given figure , the arms of 2 angles are parallel if angle ABC= 70°
find the angle DEF and angle DGC​

Answer 1

Step-by-step explanation:

AB||DE

angle ABC DEF___Corresponding angles

but angle ABC=70°____Given

angle DEF=70°

angle ABC=angle DGC___Corresponding angles

angle DGC=70°

Answer 2

Answer :

• Here BA || ED (Given in question)

• Now BC || EF (Given in diagram)

• Hence, $\sf \angle ABC = \angle$ DEF = 70°

• Now, BA || GD and EG || GC (Given in diagram)

• Hence, $\sf \angle ABC = \angle$ DGC = 70°

therefore, DEF = 70° = DGC

I hope it helps you ❤️✔️
