A triangle has side lengths of 12 cm, 5 cm, and 9 cm. Classify it as acute, obtuse, or right.

Obtuse

Angle ∠ A = α = 114.975° = 114°58'30″ = 2.007 rad

Angle ∠ B = β = 22.192° = 22°11'30″ = 0.387 rad

Angle ∠ C = γ = 42.833° = 42°50' = 0.748 rad

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.

understand that i don't know the answers

will someone answer his question
