Question

What is the value of x
possible answers are:
A. x=3
B. x=18
C. x=30
D. x=9

Answer 1

A

Explanation:

MB is a perpendicular bisector to JK, thus triangle is equilateral/ isosceles, hence

MJ = MK

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 → A
