i have to find the values of the variables in these two lines that connect together...geometry?

Question

(6y-10) degrees
and
(6y+10)

one of the lines is just straight (180) degrees
and the other is just slightly slanted towards the left but its connected to the straingt line

\
\
___________\_____________
(6y-10)degree (6y+10)degree



that is a diagram

when you answer my question plz tell me how to with detailed instructions...i dont want to just know the answer i want to know how to get it


THANK YOU VERY MUCH!!!!!!!

Answer 1

When one straight line stands on another straight line, two angles are formed whose sum is 180 degrees or two right angles.

So we have 6y-10 +6y +10 = 180
12y = 180
y = 15
6y-10 = 80 degrees, and 6y+10 = 100 degrees

If the two angles that are formed are equal to each other, then they both equal 90 degrees and the lines are said to be perpendicular.
