Step-by-step explanation:
x = 7
y = -3

Answer:
see explanation
Step-by-step explanation:
Point A is the Incentre of the triangle
This is the point where the 3 angle bisectors intersect
The incentre is equally far away from the triangle's 3 sides , then
AM = AL = 6
2+34=4(x+5)
distribute
2+34 = 4x+20
combine like terms
36 = 4x+20
subtract 20 from each side
16 = 4x
divide by 4
4 = x
Answer: x=4
Y^a+b
The top right one. Hope this helps:)
