Question

Thanks so much to anyone who can help!!

Answer 1

x = 3

Explanation:

using the perpendicular bisector theorem B

MB is the perpendicular bisector of JK and JB = KB

then Δ MJK is isosceles with legs being congruent , that is

MJ = MK , so

9x - 18 = 3x ( subtract 3x from both sides )

6x - 18 = 0 ( add 18 to both sides )

6x = 18 ( divide both sides by 6 )

x = 3
