Question

the side of smaller triangle is 8 10 12 out of 2 similar triangle . if the perimeter of larger triangle is 180 find sides of larger triangle

Answer 1

let side of small triangle be a,b,c
and large triangle x,y,z
abc<-->xyz

$\frac{a}{x} = \frac{b}{y} = \frac{c}{z} = \frac{(a + b +c) }{(x + y + z)}$
so by this
8/x=10/y=12/z=30/180

so x=(8*180)/30=48
y=(10*180)/30=60
z=(12*180)/30=72
hope it helps
