Question

In the given fig. DE || BC, ∟ADE =70° and ∟BAC=50°, then angle

∟BCA = ______
(please explain how)​

Answer 1

Answer:

< BCA=60°

Step-by-step explanation:

• Given, <BAC=50°
• <ADE= 70°

therefore, <ABC= 70° (because,they are corresponding angles since DE is parallel to BC)

• now,as the sum of angles of triangle is 180,

<BCA=180-(70+50)

=180-120

= 60°
