Question

The angles of triangle are in the ratio 1:2:3 . find their measure in degree

Answer 1

Answer:

the answer is 30, 60 , 90

Step-by-step explanation:

let the angles be in the ratio of x,2x,3x

so x+2x+3x=180

6x=180

×=180/6 = 30

therefore

1st angle is 30 degree

2nd angle is 30 × 2 = 60 degree

3rd angle is 30 ×3 = 90

Answer 2

Answer:

Let the common ratio be 1x,2x,3x

Sum of all angles of triangle=180°

1x+2x+3x=180°

6x=180°

x=180°÷6

x=30°

Hence,

angle 1=1x

=1×30°=30°

angle 2=2x

=2×30°=60°

angle 3=3x

=3×30°=90°
