Question

find all the three angles of the triangle shown below. is it possible to have such a triangle ? justify​

Answer 1

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 2

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.
