Answer:
Step-by-step explanation:
LETS L ( x,7) be (X1, y1) and M (1,15) be (x2,y2)
By distance formula,
d(L,M) = root (x2-x1)^2 + (y2-y1)^2
10 = root (1-x)^2 + (15-7)^2
10=root (1-x)^2 + (8)^2
Squaring both sides
100= (1-x)^2 +64
100-64=(1-x)^2
(1-x)^2=36
1-x=+- 6 (taking square root)
1-x=6 or 1-x= -6
X=1-6 or x=1+6
X= -5 or x =7
