What is the value of (tan 65° - tan 35°) / 1 + tan 65°tan 35°? 0 0 V3/3

goldenfox [79]

Answer:

$\frac{ \sqrt{3} }{3}$

Step-by-step explanation:

We know that tangent angle addition formula is

$\tan(a - b) = \frac{ \tan(a) - \tan(b) }{1 + \tan(a) \tan(b) }$

This is in form already. Based on the value, a is 65 and b is 35 so let just subtract that

$\tan(65 - 35) = \tan(30)$

W e know that tan 30 is

$\tan(30) = \frac{ \sin(30) }{ \cos(30) } = \frac{ \frac{1}{2} }{ \frac{ \sqrt{3} }{2} } = \frac{1}{ \sqrt{3} } = \frac{ \sqrt{3} }{3}$

Ksivusya [100]

Answer:

C. The same number of guests attended Rick and Tom's party.

Step-by-step explanation:

Let R and T represent the number of guests at Rick's and Tom's parties, respectively. The charges Rick and Tom paid are equal, so we have ...

65 +25R = 40+25+25T

25R = 25T . . . . . . . . . . . . subtract 65

R = T . . . . . . . . . . . . . . . . . divide by 25

The number of guests at each party is the same.
