Question

in a triangle ABC, angles A, B, C, are in the ratio 1: 2: 3. Find the angles.

Answer 1

Answer:

a = 30 degree

b = 60 degree

c = 90 degree

Step-by-step explanation:

let the ratio between a,b and c be x,2x and 3x

According to the question,

x + 2x +3x = 180 degree

6x = 180 degree

x = 180 degree/ 6

x = 30

a = x= 30 degree

b = 2x= 60 degree

c = 3x= 90 degree

Answer 2

Answer:

30,60,and90

Step-by-step explanation:

x+2x+3x= 180( angle sum property)

6x=180

x=180/6

x=30

2x=60

3x=90
