Using the given endpoint R (8,0)and the midpoint M (4,-5) , the other endpoint S is (0,-10)
Explanation :
Use the given endpoint R and the midpoint M of segment RS
R (8, 0 ) and M (4, -5 )
Let 'S' be (x2,y2)
Apply the midpoint formula
Endpoint R is (x1,y1) that is (8,0)
Substitute the values and make it equal to M(4,-5)
So other endpoint S is (0,-10)

Step-by-step explanation:
Thus L.H.S = R.H.S that is 2/√3cosx + sinx = sec(Π/6-x) is proved
We have to prove that
2/√3cosx + sinx = sec(Π/6-x)
To prove this we will solve the right-hand side of the equation which is
R.H.S = sec(Π/6-x)
= 1/cos(Π/6-x)
[As secƟ = 1/cosƟ)
= 1/[cos Π/6cosx + sin Π/6sinx]
[As cos (X-Y) = cosXcosY + sinXsinY , which is a trigonometry identity where X = Π/6 and Y = x]
= 1/[√3/2cosx + 1/2sinx]
= 1/(√3cosx + sinx]/2
= 2/√3cosx + sinx
R.H.S = L.H.S
Hence 2/√3cosx + sinx = sec(Π/6-x) is proved
