Question

The perimeter of a triangle is 8a + 9b – 5c. Two of its sides are 2a – 3b + 4c and 6c – 4a + 8b. Find the third side. *

Answer 1

Answer:

perimeter =sum of all sides

Step-by-step explanation:

let third side be X

2a-3b+4c+6c-4a+8b=sum of two sides

=5b+9c-2a

third side =perimeter - two sides

(8a +9b-5c)-(5b+9c-2a)

10a+4b-14c

hence third side is 10a+4b-14c

Answer 2

HERE IS YOUR ANSWER MATE....;

THIRD SIDE = 10A +4B-14C

HOPE ITS HELPFUL.....:-)
