If `alpha + beta = 90^@` and `beta + gamma = alpha` then `tanalpha-tanbeta=?`

If alpha+beta=90^(@) and beta+gamma=alpha then tan alpha-tan beta=?

If alpha +beta = 90^@ and alpha:beta = 2 : 1 , then tanalpha : tanbeta is equal to (A) 1 : 3 (B) 2 : 3 (c ) 3 : 2 (D) 3 : 1

If alpha+beta=(pi)/(2) and beta+gamma=alpha, then tan alpha equals

If alpha+beta=(pi)/(2) and beta+gamma=alpha then tan alpha equals

If alpha+beta=(pi)/(2) and beta+gamma=alpha then tan alpha=

Let alpha=som^(-1)((36)/(85)),beta=cos^(-1)((4)/(5)) and gamma=tan^(-1)((8)/(15)) then cot alpha+cot beta+cot gamma=cot alpha cot beta cot gammatan alpha tan beta+tan beta tan gamma+tan alpha tan gamma=1tan alpha+tan beta+tan gamma=tan alpha tan beta tan gammacot alpha cot beta+cot beta cot gamma+cot alpha cot gamma=1
