Answer:
3x+7
Step-by-step explanation:
perimeter= sum of 3 side
one side = perimeter- sum of other two sides
= 8x +9 -( 3x+1 + 2x+1)
= 8x +9 -5x -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.
