​

Answer 1

Hey Friend...

Here is the Solution.

⇒ ${\boxed{Step\:By\:Step\:Solution}}$

↓

∠ BAD = ∠BAE + ∠EAD

∠ BAD = 40° + 35°

∠ BAD = 75°

⇒ NOW

∠BAD = ∠ADC

∵ These are alternate angles

∴ CD ║ AB     -------(1)

______________

Now,

→ ∠BAE + ∠AEF

→ 40° + 140°

→ 180°

∠ BAE + ∠ AEF = 180°

∵ These are co-interior angles

→ ∴ AB ║ EF    -------(2)

______________

→→ From eq. (1) & eq. (2) ←←

____AB ║ EF ║ CD______

.

Therefore, CD ║ EF
