`If x/(tan (theta + alpha)) = y/(tan (theta + beta)) = z/tan(theta + gamma), "prove that"`
`(x+y)/(x-y)sin^(2) (alpha - beta) + (y + z)/(y - z) sin^(2) (beta - gamma) + (z + x)/(z-x) sin^(2) (gamma - alpha ) = 0`

Text Solution

Verified by Experts

The correct Answer is:
(x + y)/(x - y) sin^(2) ( alpha - beta) + (y +z)/(y-z) sin^(2) (beta - gamma) + (z + x)/(z - x) sin^(2) (gamma - alpha) =0`
