Question

Help!!!! find the exact value of the expression

Answer 1

\[\frac{ \tan 165-\tan 45 }{ 1+\tan 165\tan 45}\]

Answer 2

you have formula for this , = tan ( 165 - 45) = tan 125

Answer 3

= - 0. 78

Answer 4

how did u get tan 25

Answer 5

tan 125 , not tan 25

Answer 6

ok, my bad, wrong, sorry, friend,

Answer 7

I redo

Answer 8

how did u get that

Answer 9

tan (120) = 0.71

Answer 10

not problem

Answer 11

I told before, you have formula for this, It is \[\tan (a-b) = \frac{ \tan a - tanb }{ 1+ \tan a \tan b }\]
your a = 165
b = 45

Answer 12

okay thats how we got o.71

Answer 13

yes
