Question

Find the angle of a triangle which are in ration 4:3:2.​

Answer 1

let the angles be 4x, 3x and 2x

we know that sum of angles if triangle is 180°

so, 4x+3x+2x = 180°

=> 9x = 180°

=> x = 20°

so the angles are 80°, 60°, 40°

please mark me as brainliest

Answer 2

Answer:

4x=4*20=80⁰

3x=3*20=60⁰

2x=2*20=40⁰

Step-by-step explanation:

4x+3x+2x=180⁰(ASP of ∆)

9x=180⁰

x=180/9

x=20⁰
