Question

In triangle ABC, A:B:C = 1:2:3. Find the angles and identify the type of triangle. ​

Answer 1

Answer:

let angle A be - 1x

let angle B be - 2x

let angle C be - 3x

so

triangle ABC

A+B+C=180

1x+2x+3x=180

6x=180

x=180/6

x=30

A= 1 × x = 1×30=30

B=2×x= 2×30=. 60

C=3 × x= 3× 30 = 90

it is a Scalene triangle because all the sides are unequal
