Question

The Ratio of a triangle is 3. 4 5 find all the angles

Answer 1

let all the Angles be x
And we know that sum of all angles=180
hence
3x+4x+5x=180
12x=180
x=180/12
x=15
This 3x=45
4x=60
5x=75

Answer 2

Heya !!!

Given that ratio of three angles of a triangle is 3:4:5


Sum of ratio = 3+4+5 = 12
Sum of the angles of triangle = 180°

Now,
First Angle = 3/12 × 180 = 45°
Second Angle = 4/12 × 180 = 60°
Third Angle = 5/12 × 180 = 75°


Hope you got it
