Question

if a:b:c=2:v6:v3+1 then angle c​

Answer 1

Step-by-step explanation:

Let, a, b and c are the angles of a triangle. So, as we know the highest sum of triangles three angle is 180°

So that, a+b+c= 180°

Or, 2+6v+3v+1= 180

Or, 9v+3= 180

Or, 9v=180-3= 177

Or, v= 177/9= 19.67(almost)

So now, c= 3v+1= 3(19.67)±1= 60

if calculate the whole sum in a scientific calculater, you will get accurate 60°...

So, c= 60°Or, π/3.
