Question

The perimeter of a triangle is 49x +20 and two of its sides are 23x+3 and 7x+15 .Find

the third side of the triangle .​

Answer 1

Answer:

The third side of the triangle is 19x + 2

Step-by-step explanation:

We know, Perimeter of triangle = sum of three sides

Acc to ques,

Perimeter of triangle = 49x +20

a = 23x + 3

b = 7x +15

c = ?

so, Perimeter = a + b + c

49x + 20 = 23x + 3 + 7x + 15 + c

49x + 20 = 30x + 18 + c

49x + 20 - 30x - 18 = c

19x + 2 = c

=> c = 19x +2
