Question

how do i find the solution to angle lines

Answer 1

post a specific question

Answer 2

Two lines intersect to form two pairs of vertical angles

Answer 3

@vero18191 it depends on the type of the equation, do u have one?

Answer 4

my question is: what is an "angle line"?

Answer 5

in that case, yowzer answered.

notice that a straight line is 180 degrees
in your picture a+146 = 180 (together the two angles add up to 180)
notice that 146+c= 180 (also a straight line)
so a=c
a and c are vertical angles.
you can see what the unlabeled angle is?

Answer 6

to find a using
a+146=180
subtract 146 from both sides of the equation, like this
a+146-146= 180-146
simplify: on the left 146-146 is 0 and a+0 is a
on the right 180-146= you figure it out
