Question

please it is quite bit urgenttt​

Answer 1

Step-by-step explanation:

( a ) To find the length of AB , we use distance formula

d = √ [ ( x2 - x1 ) ² + ( y2 - y1 )² ]

Here, x2 = 1 ; x1 = -2 ; y2 = 5 ; y1 = 1

AB = √ [ ( 1 + 2 )² + ( 5 - 1 )² ] = √ [ (9) + (16) ] = √ 25

AB = 5 units

( b ) and ( c ) refer to the image my dear friend ✌
