Question

Chapter- Lines and Angles
please step by step explanation​

Answer 1

Answer:

Hence, Angle 1=42° , 2=42° , 3= 138° , 4=42° , 5= 138°

Answer 2

$\bf\underline{\underline{\green{SOLUTION:-}}}$

Answer

• ∠2= 42°
• ∠3= 138°
• ∠4= 42°
• ∠5= 138°

Given

• ∠1 = 42°

To Calculate

• ∠2,∠3,∠4,∠5

Step by step explanation

• ∠1 = 42°

∠1=∠4 ( Corresponding Angles)

${\boxed{\red{\tt{∠4= 42° }}}}$

∠4+∠3=180°( L.P)

42° +∠3=180°

∠3= 180-42

${\boxed{\red{\tt{∠3= 138° }}}}$

∠4=∠2 ( V.O.A)

${\boxed{\red{\tt{∠2= 42° }}}}$

∠3 = ∠6 ( Corresponding angles)

∠6 = 138°

∠6 = ∠5 ( V.O.A)

${\boxed{\red{\tt{∠5 = 138° }}}}$

$\bf\underline{\underline{\green{HENCE:-}}}$

• ∠2= 42°
• ∠3= 138°
• ∠4= 42°
• ∠5 = 138°
