1. Answer:

   hey here is your answer

   pls mark it as brainliest

   so here we go

   Step-by-step explanation:

   let the base of isoceles triangle be x and equal sides be y

   so according to first condition

   x=3y+5 (1)

   now we know that perimeter of isoceles triangle is 2×side+base

   so second condition says that

   2y+x=75 (2)

   substitute value of x from (1) in (2)

   we get 75=2y+3y+5

   ie 5y=70

   so y=14

   now substitute value of y in (1)

   we get x=3y+5

   x=(3×14)+5

   ie x=42+5

   so x=47

   hence length of each equal side of isoceles triangle is 14 cm while its base is 47 cm
