If `x+y+z=pi,tanxtany=2 and tanx+tany+tanz=6` then `z=`

If x + y + z = pi , tanx tany = 2 tanx + tany + tanz = 6 , then z equals :

If x+y+z=pi,,tan x tanz=2and tanytanz=18,then tan^(2)z=

If x+y+z=pi,,tan x tanz=2and tanytanz=18,then tan^(2)z=

If x+y+z=pi,,tan x tanz=2and tanytanz=18,then tan^(2)z=

If x+y=pi/4 and tanx+tany=1, then

In the following questions, write 'T' for truee and 'F' for false statements. If tanx + tany = 5 and tanx. tany =1/2 then cot(x+y) = 10

If x+y =pi/4 and tanx + tany=1 , then

Prove tanx+ tany+ tanz=tan xtany tanz if x+y+z = pi

Prove tanx+ tany+ tanz=tan xtany tanz if x+y+z = pi

If x,y,z are variables and 3tan x+4tany+5tanz=20, then the minimum value of tan^(2)x+tan^(2)y+tan^(2)z, is
