Answer 2

Answer:

Let the first angle be=5x

let the second angle be=3x

let the third angle be=1x

sum of all the angles of the triangle=180⁰

5x+3x+1x=180°

9x=180⁰

x=180⁰/9

x=20⁰

First angle=5x=5(20)=100⁰

Second angle=3x=3(20)=60⁰

Third angle=1x=1(20)=20⁰

Proove:

sum of all the angles of the triangle=180⁰

5x+3x+1x=180⁰

100⁰+60⁰+20⁰=180⁰

180⁰=180⁰
