Question

The angle in a triangle are in the ratio 2:3:4. Determine the angle.​

Answer 1

Answer:

answer - 40,60,80.

Step-by-step explanation:

2x+3x+4x=180

9x=1809x=180

x=20x=20

The value of x is 20.

2x=2(20)=402x=2(20)=40

3x=3(20)=603x=3(20)=60

4x=4(20)=804x=4(20)=80

Answer 2

Given⤵️

▪︎ratio of angle of triangle 2:3:4

To find⤵️

▪︎angle of triangle

solution⤵️

➡️ we know that sum of all angles of triangle is 180⁰

let 1st angle be 2x

2nd angle be 3x

3rd angle be 4x

hence from property of triangle

》2x + 3x + 4x = 180⁰

= 9x = 180⁰

= x = 20⁰

so ist angle be 2x = 2× 20⁰= 40⁰

2nd angle be 3x = 3× 20⁰ = 60⁰

3rd angle be 4x = 4× 20 = 80⁰

properties of triangle-

☆it have three vertex, three angle and three side.

☆ sum of all angles is 180⁰

☆ sum of exterior angles is equal to opposite two interior angle.
