Atriangle has two angles measuring 42 and 73 calculate the third angle of the triangle

The measure of third angle of the triangle is 65°

Step-by-step explanation:

Measure of one angle of the triangle is given to be 42

Measure of second angle of the triangle is given to be 73

Let the measure of the third angle of the triangle be x

Now, By using the angles sum property of a triangle, We have :

Sum of all the three angles of a triangle is always supplementary

⇒ ∠1 + ∠2 + ∠3 = 180°

⇒ 42° + 73° + ∠3 = 180°

⇒ 115° + ∠3 = 180°

⇒ ∠3 = 180° - 115°

⇒ ∠3 = 65°

Hence, The measure of third angle of the triangle is 65°

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.
