Answer: 51
Work Shown:
Use the converse of the SSS (side side side) similarity theorem. This says that if two triangles are similar, then their sides are in proportion
OH/WI = HJ/IM ... see the attached diagram below
48/64 = x/68
48*68 = 64x ... cross multiply
3264 = 64x
64x = 3264
x = 3264/64 .... divide both sides by 64
x = 51
