Question

For what value of 'x' will the lines l and m be parallel to each other?

Answer 1

Step-by-step explanation:

Since both are corresponding angles,

Hence both are equal..

So (3x - 20 )° = (2x + 10)°

3x - 2x = 10° + 20°

x = 30°

Therefore, when the value of x will be 30°, then l will be parallel to line m...
