Answer:
Step-by-step explanation:
if the base=x
length of one leg is =4x-6
length of the other leg is also =4x-6 (isosceles)
P=x+4x-6+4x-6=51
9x-12=51
9x=51+12
9x=63
x=63/9=7
x=7
12/66--->x/22
12/66--->4/22 (almost 4/20 if you know what I mean)
Step-by-step explanation:
AB(x)/DE=BC/EF
AB/25=28/20
20AB=28×25
20AB=700
AB=700/20
AB=35
SO x=35
