Question

In the given figure L1 +L3= 120°, L2+L4 is equal to?​

Answer 1

Step-by-step explanation:

Since L1 and L3 arw vertically opppsite angles therefore ,

L1 = L3 = 120÷2= 60°

and L2 and L4 are vertically opposite angles , therefore,

L2 = L4

Since L1 + L2 + L3 + L4 = 360°

60° + L2 + 60° + L4 = 360°

120° + 2 L2 = 360°

L2 = 240°÷2

L2 = 120°

and L4=120°

Answer 2

Answer:

Step-by-step explanation:

Since L1 and L3 arw vertically opppsite angles therefore ,

L1 = L3 = 120÷2= 60°

and L2 and L4 are vertically opposite angles , therefore,

L2 = L4

Since L1 + L2 + L3 + L4 = 360°

60° + L2 + 60° + L4 = 360°

120° + 2 L2 = 360°

L2 = 240°÷2

L2 = 120°

and L4=120°
