Question

in exersice 9 and 10, identify the ssegment bisector of XY. Then find XY

Answer 1

9) The segment bisector is the ray that is dividing XY into XM and MY, which is MN. The segment XY is equal to the sum of each section:

$(3x+1)+(8x-24)\\ 11x-23$

10) The segment bisector is the line dividing XY into XM and MY, which is line n. The segment XY is equal to the sum of XM and MY:

$(5x+8)+(9x+12)\\ 14x+20$
