  • Here, the two angles are equal.
  • So, it is an isosceles triangle.
  • So, the two opposite sides to the equal angles will be equal.
  • Therefore, XY = YZ
  • [tex]15 = 4x + 3 \\ = > 4x = 15 - 3 \\ = > 4x = 12 \\ = > x = 3[/tex]
  • Therefore, YZ = 4x + 3 = 4(3) + 3 = 12 + 3 = 15

Hope you could get an idea from here.
