Question

for what value of x will the lines l and m be parallel to ​

Answer 1

Answer:

therefore for the lines to be parallel, the value of X =30

Answer 2

Answer:

x = 30°

Step-by-step explanation:

     3x-20° = 2x+10°                [∵Corresponding angles]

or, 3x-2x = 10°+20°

or, x = 30°

Now,   3x-20°

        = 3(30°)-20° = 90°-20° = 70°

         2x+10°

       = 2(30°)+10° = 60°+10° = 70°

Hence, they are corresponding angles. Thus, the value for both the angles are equal.
