Question

in the given figure angle ABC is 65 and bce is 30 dce is 35 and angle 145 show that Ab parallel ef

Answer 1

Step-by-step explanation:

Given, ∠ABC = 65°.

⇒ ∠ BCD = ∠BCE + ∠DCE

               = 30 + 35

               = 65°

So, ∠ABC = ∠BCD.

∴ CD ║ AB.    ---- (i)

⇒ ∠ECD + ∠CEF = 35 + 145

                            = 180°

∴ CD ║ EF    ----- (ii)

From (i) & (ii), we get

AB ║ EF.
