Question

The distance between points A(-3,-4) and c(7,b) is 10 then b = ____​

Answer 1

Step-by-step explanation:

(x1-x2)^2+(y1-y2)^2=d^2

x1=-3, y1=-4,x2=7,y2=b,d=10

(-3-7)^2+(-4-b)^2=(10)^2

(-10)^2+(4-b)^2=100

100 +(4-b)^2=100

(4-b)^2=0

4-b=0

b=4

Answer 2

Step-by-step explanation:

use this formula

(AC)^2 =√(x2-x1)^2+ (y2-y1)^2
