- 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.
Doubt clarification - use comment section.
