Question

PLs answer this will mrk as rainliest

Answer 1

According to the definition of corresponding angles ,

$\implies \: (2x + 20) = (3x - 10) - - - - (corresponding \: angles) \\ \: \implies3x - 2x = 20 + 10 \\ \: \implies \: x = 30.$

Therefore,the value of x is 30.

Answer 2

as we know

$l1 || l2 \\ \\ thats \: why. \\ \\ 2x + 20 = 3x - 10 \\ \\ 20 + 10 = 3x - 2x \\ \\ 30 = x$

I hope this will be help you
