Question

The perimeter of an isosceles triangle 43/4cm.if one of its side is 17/6 cm,find the third side

Answer 1

Answer:61/12

Step-by-step explanation:

let all the 3 sides be a,b,c

where a and b are equal

p= a+b+c

43/4=17/6+17/6 + c

43/4= 17/3+ c

43/4-17/3= c

129-68 = c

12

61/12=c

Answer 2

Answer:

Step-by-step explanation:

Given :-

Perimeter of triangle = 43/4

one side of triangle = 9/4

Let the traingle is ABC

We know that in isosceles triangle 2 sides are equal.

Perimeter = AB + BC + CA

43/4 =  9/4 + BC + 9/4      

43/4 = 18/4 + BC            (AB = CA)

43/4 - 18/4 = BC

25/4 = BC

BC = 25/4    (Answer)

So, The third side of triangle is 25/4.
