Question

If the distance between the points (0,1) and (8,k) is 10 units then find k​

Answer 1

Step-by-step explanation:

A(0,1) B(8,K)

Distance =10

(10)2=(0-8)2 +(K-1)2

100 =64 +K2 - 2K +1

100=65+K2-2K

100-65 =K2-2K

35=K2-2K

K2-2K-35=0

K2-7K+5K -35=0

K(K-7) +5(K-7)=0

(K+5)and (K-7)=0

K+5=0 and K-7=0

K=-5 and K=7

thus value of K will be 7 or -5
