Answer:
X=75
Y=110
Step-by-step explanation:
A straight line is 180, so add the equations that make a line and set them equal to 180
x+20+x+10=180
Combine like terms
2x+30=180
Subtract 30 from both sides
2x=150
Divide by 2
X=75
Same for y
y+y-40=180
2y-40=180
Add 40 to both sides
2y=220
Divide by 2
Y=110

we have to firstly apply the distance formula to find the length of sides of the triangle
distance formula = 
So length AB = 
BC= 
AC = 
Now perimeter = AB+BC+AC = 
Plug in calculator
perimeter= 11.4 units
