Question

the three angles of triangles are in the ratio 5: 4: 3 find all angle of triangle​

Answer 1

Answer:

Let the ratio of angles of ∆ be 5x : 4x : 3x .

We know that the sum of int. angles of a ∆ equals to 180° .

A/q

5x + 4x + 3x = 180

=> 12x = 180

=> x = 180/12

= 15

Hence,

1st angle = 5x = 5×15 = 75°

2nd angle = 4x = 4×15 = 60°

3rd angle = 3x = 3×15 = 45°

Answer 2

Step-by-step explanation:

let anglee ve in the ratio 5x 4x and 3x

Now

5x+3x+4x=180

=)x =15

angles are 75 45 60
