Question

Find the value of x. Diagram included below

Answer 1

two lines are parallel

Answer 2

and two skew line cutting them are called transversal line here

Answer 3

so using the property of parallel lines
sum of interior angle =180 degree
4x+x+30=180
5x+30=180
5x=150
x=30

Answer 4

@Rwelch u got it ??

Answer 5

how'd you know to add the =180?

Answer 6

that is the property of parallel line

Answer 7

HERE is the property if a transversal line cut the two parallel lines than sum of its corresponding interior angle equal to 180

Answer 8

A & B are corresponding interior angle
C & D is other pair of corresponding interior angle
A+B=180
C+D=180
remember it alwys true

Answer 9

now ???
