the sides of a triangle measure 4,+8 and 10.
if the smallest side of a similar triangle measures 12,then we use proportion to find the remaining sides of this triangle
let the remaining sides of this triangle be b and c
4%3A8 is equal to 12%3Ab
so, we have 4%3A8=12%3Ab........solve for b
4b=12%2A8
b=%2812%2Across%288%292%29%2Fcross%284%29
b=12%2A2
b=24
and
8%3A10=24%3Ac
8c=24%2A10
c=240%2F8
c=30
