Question

if the angels of a triangle are (3x), (2x-7) and (4x-11) then find the value of x​

Answer 1

Answer:

Step-by-step explanation:

total angle=180 degree

equation=

3x+2x-7+4x-11=180

9x=180+11

9x=191

x=21.2

1 angle = 21.2 X 3

2 angle = 21.2X2

3 angle = 21.2 X 4

Answer 2

$\huge{Answer :-}$

____________________________

Given, ∠A , ∠B , ∠C are interior angles of a triangle

∠A = 3x

∠B = 2x - 7

∠C = 4x - 11

Now,

∠A + ∠B + ∠C = 180°
[Angle sum property in a triangle]

3x + 2x - 7 + 4x - 11 = 180°

9x - 18 = 180°

9x = 180 - 18

9x = 162

==> $\boxed{x = 18}$
