I am please help on 14 and 15 please actually answer please

14) x = 150°

15) t = 61°

Step-by-step explanation:

14) angles that form a straight line are referred to as a 'linear pair' and are supplementary; their sum is 180°

15) these angles are complementary; their sum is 90°

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.
