Answer 2

Answer:

answer is 45 90 and 45

Step-by-step explanation:

let the common multiple be x

first angle =1x

second angle=2x

third angle=1x

now

1x+2x+1x=180 degree(sum of angles of the triangle is 180 degree)

4x=180

x=180/4

x=45

now entering the value

first angle=1x=45

second angle =2x=2 into 45= 90 degree

third angle=1x=45degree
