HELPPPPP! In the image shown, line n is a transversal cutting parallel lines l and m.

angle 3 = 80°

Step-by-step explanation:

here , angle 3 = angle 7 ( corresponding angles )

so ,

=》 x + 50 = 2x + 20

=》2x - x = 50 - 20

=》 x = 30°

so angle 3 = x + 50 = 30 + 50 = 80°

i hope it helped.

8 minutes, 30 seconds, by the look of the graph.

Step-by-step explanation:

At a distance of 10 inches, 1 minute has passed.

So multiply that by 8.5, and you have 85 inches travelled over 8 minutes, 30 seconds.
