Answer:
Step-by-step explanation:
line perpendicular to ax+by=c is
bx-ay=k, where k is a constant.
if it passes through (-1,2) then
b(-1)-a(2)=k
or k=b-2a
so reqd. eq . is bx-ay=b-2a
ABC is an isosceles triangle.
Sides : AB = BC
3 x - 7 = 2x
3 x - 2 x - 7 = 2 x - 2 x
x - 7 = 0
x - 7 + 7 = 0 + 7
x = 7
Segment AC:
AC = 3 * 7 - 7 = 21 - 7 = 14
Answer: C ) 14
