Question

The perimeter of a triangle is 8x + 9 and the two sides are 3x + 1 and 2x + 1 . Find the Third Side

Answer 1

Answer:

the answer is

Step-by-step explanation:

perimeter of triangle =a+b+c

let take the other side of triangle be=x

3x+1+2x+1+x=8x+9

x=8x+9-5x-2

x=3x+4

Answer 2

Answer:

Perimeter of the triangle = (8x + 9)

(3x + 1) + (2x + 1)+ Third side = (8x + 9)

(5x + 2) + Third side = (8x +9)

Third side = (8x + 9) - (5x + 2)

Third side = 8x + 9 - 5x - 2 = 3x +

✅ Hence the third angle of the triangle is 3x+7.
