Question

calculate the angles of a triangle if they are in the ratio 4:5:6 ​

Answer 1

Step-by-step explanation:

Let the angles be 4x, 5x, 6x

then according to angle sum property,

4x+5x+6x=180degree

15x=180

x=180/15

x=12degree

Then the angles of the triangle aree

4×12= 48degree

5×12= 60degree

6×12= 72degree

Answer 2

let the angles of the triangle = 4x....5x.....6x...

So... 4x + 5x + 6x = 180 (angle sum of triangle)

15x = 180

x = 180/15

x = 12

so......

4x = 4×12 = 48

5x = 60

6x = 72 degrees
