Answer:
Suppose 5:6:7 = 5x:6x:7x
The area of triangle = 180
It means 5x+6x+7x = 180
18x = 180
x = 10
5x = 5 × 10 = 50
6x = 6 × 10 = 60
7x = 7 × 10 = 70

Answer:
50° , 60° and 70°
Step-by-step explanation:
let angles be 5x , 6x and 7x
we know sum of angles of a triangle = 180°
5x + 6x + 7x = 180°
x = 10°
putting the value of x in 5x , 6x and 7x
we get ,
5x = 50°
6x = 60°
7x = 70°
