Question

4. Find the angles of a triangle which are in the ratio 4:3:2.​

Answer 1

Answer:

let the angle be 4x,3x & 2x

we know the sum of the angle of triangle is 180

therefore 4x + 3x + 2×

=9x = 180

x = 20 therefore angle of triangle is 80' 60 ' 40

Answer 2

Answer: 80°; 60° ; 40°

______________

Step-by-step explanation:

Let the common factor be x.

Ratio :- 4: 3 : 2

As we know, The sum of all angles of the triangle is 180°.

Now,

4x + 3x + 2x = 180°

=> 9x = 180°

=> x = $\dfrac {180°}{9}$

$\boxed {\boxed { x = 20°}}$

➡ Put the value of x in each angle.

4x = 4 × 20 = 80°

3x = 3 × 20 = 60°

2x = 2 × 20 = 40°
