Question

In the figure l ∥ m , if ∠1=70°, find ∠2​

Answer 1

Answer:

Angle 2 = 180° - 70° = 110°

Answer 2

Given :

• l || m ,
• ∠1 = 70°

To Find :

• ∠2

Solution :

• ∠1 = 70°

$\longrightarrow$ In this given diagram, ∠1 and ∠2 are Linear pairs

$\longrightarrow$ And l || m ,

$\longrightarrow$ Thus,

$\longrightarrow$ Sum of all interior angles in Linear pair = 180°

$\longrightarrow$ Hence,

• ∠1 + ∠2 = 180°

• 70° + ∠2 = 180°

• ∠2 = 180° - 70°

• ∠2 = 110°

So, ∠2 = 110°

I hope it helps you ❤️✔️
