Question

Base of an isosceles triangle is five more than three times the equal sides and perimeter of the
triangle is 75 cm. Find the lengths of the sides of the triangle.

Answer 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
