Question

tan10 + tan35 / 1- tan10tan35

Answer 1

this is probably either the addition angle formula, or the subtraction
i can never keep them straight, look it up
my guess is the addition, so it is probably \[\tan(45^\circ)\] but i would not swear to it

Answer 2

So can you walk me thru the steps or no?

Answer 3

Help plz

Answer 4

Trigonometry Identities I believe this is

Answer 5

$$ \large\tan ( A + B ) = \frac{\tan A + \tan B }{1 - \tan A \cdot \tan B } $$

Answer 6

Which wud b A and B

Answer 7

$$ \large\tan ( A + B )
= \frac{\tan A + \tan B }{1 - \tan A \cdot \tan B }
\\~\\
\large\tan ( 10 + 35 )
= \frac{\tan 10 + \tan 35 }{1 - \tan 10 \cdot \tan 35 }

$$

Answer 8

but tan(10 + 35) = tan(45) = 1

Answer 9

so then tan 45 = tan 45/1- tan 45

Answer 10

not quite.
tan 45 = tan(10 + 35) = ( tan 10 + tan 35) / ( 1- tan 10 * tan 35)

the point here is that tan 45 is a well known angle ,
so you're basically done at that point.
tan 45 is 1

Answer 11

this is a reverse logic problem

Answer 12

you wouldn't use this formula to find tan 45, because it makes finding tan 45 more complicated

Answer 13

so the answer is tan=1

Answer 14

$$ \Large
\frac{\tan 10 + \tan 35 }{1 - \tan 10 \cdot \tan 35 }= \tan ( 10 + 35 ) = \tan(45) = 1
$$
