" 82.If "tan alpha=(x)/(x+1)" and "tan beta=(1)/(2x+1)," then "alpha+beta" is "

If tan alpha=(x)/(x+1) and tan beta=(1)/(2x+1), then alpha+beta is equal to pi/2(b)pi/3(c)pi/6(d)pi/4

If tan alpha=(x)/(x+1) andtan beta=(1)/(2x+1), then alpha+beta is equal to (pi)/(2) b.(pi)/(3) c.(pi)/(6) d.(pi)/(4), then alpha+beta

If tan alpha=(1)/(3) and tan (beta)=(1)/(2) then tan (alpha+beta)=

If tan alpha = 1/3 and tan beta = 1/2 , then: tan(alpha + beta) =

If tan alpha=(1+2^(-x))^(-1), tan beta=(1+2^(x+1))^(-1) then alpha+beta equals

If tan alpha=(1+2^(-x))^(-1), tan beta=(1+2^(x+1))^(-1) then alpha+beta equals

If tan alpha=(1+2^(-x))^(-1), tan beta=(1+2^(x+1))^(-1) then alpha+beta equals.................. A) pi/6 B) pi/4 C) pi/3 D) pi/2

If tan alpha=(1)/(1+2^(-x)) and tan beta=(1)/(1+2^(x+1)) then write the value of alpha+beta lying in the interval (0,pi/2) .

If tan alpha =(1+2^(-x))^(-1) and tan beta =(1+2^(x+1))^(-1) then the value of (alpha + beta) is-

tan alpha=(1+2^(-x))^(-1),tan beta=(1+2^(x+1))^(-1)alpha+beta
