in the figure given below if cd || ba then find ​

Answer 1

What we have to find.please say .

Answer 2

Answer:

The angles are ∠ABC=65° and ∠BCA=60°

Step-by-step explanation:

In the given figure cd || ba then

we have to find all other angles

As ∠DCE=65° and CD || BA,

⇒ ∠DCE=∠ABC    (∵corresponding angles)

⇒ ∠ABC=65°

In ΔABC

∠CAB+∠ABC+∠BCA=180°

55°+65°+∠BCA=180°

120°+∠BCA=180°

∠BCA=60°

The angles are ∠ABC=65° and ∠BCA=60°
