Answer 1

Step-by-step explanation:

$\tan(7.5) = \tan( \frac{15}{2} ) \\ \tan( \frac{15}{2} ) = \frac{1 - \cos(15) }{ \sin(15) } \\ \cos(15 ) = \cos(45 - 30) \\ \sin(15 ) = \sin(45 - 30)$

use the formulas

sin (a-b) = sina cos b - sinb cos a

cos (a-b) = cos a cosb + sina sin b

evaluate and put the values....u will get the answer

Answer 2

Answer:

tan(7.5)=tan(

2

15

)

tan(

2

15

)=

sin(15)

1−cos(15)

cos(15)=cos(45−30)

sin(15)=sin(45−30)

use the formulas

sin (a-b) = sina cos b - sinb cos a

cos (a-b) = cos a cosb + sina sin b

evaluate and put the values....u will get the answer
