Question

the base of an isosceles triangle is 4 by 3 cm the perimeter of triangle is 4 into the two by 15 cm what is the length of either of the remaining equal sides

Answer 1

base 4/3 cm, perimeter =4into 2/15cm

Answer 2

Answer:

Step-by-step explanation:

So, base = 4/3cm

Perimeter = 4*2/15 = 8/15cm

So let the equal sides be x cm

So,

x+x+4/3 = 8/15cm

2x = 8/15 - 4/3

2x = 8-20/15 (By taking the lcm as 15)

2x = -12/15

x = -12/30 (By multiplying 1/2 on both the sides)

x = -2/5

So as the sides of the triangle cannot be -ve. So the length of the remaining 2 sides is 2/5cm.

Note: you can check the answer by adding the answer with the base. Hope you will understand :)
