Question

Find the value of a when the distance between the points (3,a) and (4,1)is root 10

Answer 1

Answer:

Step-by-step explanation:

the  distance of points between (3,a) and (4,1) is 10

√(4-3)² + (1 - a)² = √10

square on both side

1 + (1-a)² = 10

(1-a)² = 9

(1-a) =√9

(1-a)=±3

1-a = -3

a =2

and 1-a = 3

    a = -2
