Question

In the given figure, if AB || CD and EF is the transversal, then the value of (x+y) is ?

Answer 1

Answer:

d) 180°

Step-by-step explanation:

The sum of (x + y) = 180°.

This is because they are cointerior angles, whose sum will always be 180°.

Hence, the correct answer will be:

d) 180°

Answer 2

QUESTION:-

In the given figure, if AB || CD and EF is the transversal, then the value of (x+y) is ?

EXPLANATION:-

x=120°   [VERTICALLY OPPOSITE ANGLES ARE EQUAL]

-----------------------------------------------------------------------

Now,

∠x+∠y=180°  [ALTERNATE ANGLES ON SAME SIDE ARE SUPPLEMENTARY]

∠x=120°  [Founded above]

120+∠y=180

∠y=180-120

∠y=60°

------------------------------------------------------------------------

So ∠x=120° and ∠y=60°

So,

→(x+y)=120+60

→(x+y)=180

Therefore:-

(x+y)=180 hence opt-[D] is required answer
