Question

If the sum of three angles is 200 and the ratio is 3:5:12 what’s the angle measured

Answer 1

Answer:

let the angles be 3x, 5x, 12x

so, 3x° + 5x° + 12x° = 200°

20x = 200

x = 200/20

x = 10

so, angle 1 :- 3x = 3(10) = 30°

angle 2:- 5x = 5(10) = 50°

angle 3 :- 12x = 12(10) = 120°

Answer 2

Answer:

30°, 50° and 120°

Step-by-step explanation:

Since the angles are in the ratio 3:5:12, then,

let the angles be 3x, 5x and 12x

ATQ,

3x+5x+12x = 200

20x = 200

x = 200/20

x = 10

therefore,

1st angle = 3x = 3×10 = 30°

2nd angle = 5x = 5×10 = 50°

3rd Angle = 12x = 12×10 = 120°

Verification,

30+50+120=200

Hence given angles are correct.
