PLS IL MAKE U THE BRAINLIEST NEED HELP WITH THIS PLEASE Use informal arguments to establish facts about the angle sum and exterior angle of triangles, about the angles created when parallel lines are cut by a transversal, and the angle-angle criterion for similarity of triangles.
In the diagram below, line a and line b are parallel, line c is a transversal, and the measure of ∠ 1 is 100°.

Is ∠3 congruent to ∠ 1? On the lines below, how you determined your answer. If it is not congruent, give the correct measure of ∠ 3.

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.

a ≈ 172.05
