Question

If the angles in a triangles are in the ratio of 1:2:3, what are the measures of angles

Answer 1

let ratio of angles be x
sum of angles of triangle=180°
x+2x+3x= 180
6x = 180
x = 180/6
x = 30°
1st angle = x = 30°
2nd angle = 2x = 60°
3rd angle = 3x = 90°

Answer 2

hello!



Let the first angle be x
Let the second angle be 2x
Let the third angle be 3x
SUM OF ALL THE ANGLES OF A TRIANGLE = 180°
THEREFORE
BTP,
x+2x+3x= 180
=> 6x= 180
=> x= 180/6
=> x= 30
Ans: The first angle = 30°
The second angle = (30*2)= 60°
The third angle = (30*3)= 90°
