no it is not possible to have such a triangle
Step-by-step explanation:
ATQ
(7-x)+(3x-5)+(2x+6)=180
→on solving
x=43°
thus (7-x)=-36
which is impossible
we cannot have a negative angle so this triangle is not possible

Answer:
It possible to have such a triangle.
Step-by-step explanation:
Sum of angles in a triangle is supplementary,
7 - x + 3x - 5 + 2x + 6 = 180°
7 - 5 + 6 - x + 3x + 2x = 180
8 + 4x = 180
4x = 180 - 8
x = 172 / 4
x = 43°
7 - x
= 7 - 43
= - 36
The value of angle cannot be negative.
Therefore, it possible to have such a triangle.
