Question

in the figure PQ||RS and l is a transverse then what will be the value of x?​

Answer 1

Answer:

40°

Step-by-step explanation:

As PQ is parallel to RS,

2x+30=x+70 (alternative angles)

2x=x+70-30

2x=x+40

X= 40 degrees

The value of x is 40°

Answer 2

x + 70° = 2x + 30° because they are co-interior angles.

Now coming to the equation,

2x - x = 70° - 30°

X = 40°

Therefore, X = 40°
