Question

please answer the question who give me right answer I will make him brainlist answer ​

Answer 1

Answer:

1. Sum of the interior angles on the same side of transversal = 120 + 60

= 180 °

As ,sum of interior angles on the same side of transversal is 180 °

a is parallel to b .

2. let angle opposite to 60 be x

x = 60° ( vertically opposite angles)

Sum of the interior angles on the same side of transversal = x + 60 = 60 + 60

= 120 °

As ,sum of interior angles on the same side of transversal is not 180 °

a is not parallel to b

3. let the angle opposite to 47° be y

y = 47 ( vertically opposite angles)

Sum of the interior angles on the same side of transversal = 47 + 133

= 180°

As ,sum of interior angles on the same side of transversal is 180 °

therefore a is parallel to b

Answer 2

Answer:

Pls mark me brainliest

Step-by-step explanation:

1. Sum of the interior angles on the same side of transversal = 120 + 60

= 180 °

As ,sum of interior angles on the same side of transversal is 180 °

a is parallel to b .

2. let angle opposite to 60 be x

x = 60° ( vertically opposite angles)

Sum of the interior angles on the same side of transversal = x + 60 = 60 + 60

= 120 °

As ,sum of interior angles on the same side of transversal is not 180 °

a is not parallel to b

3. let the angle opposite to 47° be y

y = 47 ( vertically opposite angles)

Sum of the interior angles on the same side of transversal = 47 + 133

= 180°

As ,sum of interior angles on the same side of transversal is 180 °

therefore a is parallel to b
