we know that having similar triangles so the ratio of sides,area and volume are same.

we know that
will be the area of triangle.

so 
so the ratio of the perimeter of two triangles will be

ratio of the perimeter=
Answer:
segment BC ≅ segment BC (reflexive property of congruence)
Step-by-step explanation:
Reflexive property of congruence states that an angle, line segment, or shape is always congruent to itself.

Answer:
x= 5 1/3
Step-by-step explanation:
l3x-5l=11
3x-5=11
+5 +5
3x=16
/3 /3
x=5 1/3
Answer:
sure
Step-by-step explanation:
whats it based on?

$=(a^2-10a)-(b^2+6b) +16$
$=[(a^2-2(5)a+25)-25]-[(b^2+2(3)b+9)-9]+16$
$=(a-5)^2-25-(b+3)^2+9+16$
$=(a-5)^2-(b+3)^2$
