Question

I want answer of c one ​

Answer 1

Answer:

30degree ,60degree,90degree

Step-by-step explanation:

Given

Angles are in ratio 1:2:3

Let angles be 1x, 2x and 3x

By angles sum property of triangle

Sum of all three angles of triangle =180 degree

Therefore

1x +2x +3 x = 180

6x = 180

x =180/6

x =30 degree

Therefore required angles are

1x = x = 30 degree

2x =2*30=60 degree

3x =3*30=30 degree

Note 1x can be written as x
