What is the exact value of sin (165 degrees)

anygoal [31]

Answer:

Step-by-step explanation:

Think of a value on the unit circle that is double of 165.

330 is that so we can use the double Angle Identity

$\sin( \frac{ \alpha }{2} ) = \sqrt{ \frac{1 - \cos( \alpha ) }{2} }$

Alpha is 330

$\sin(165) = \sqrt{ \frac{1 - \cos(330) }{2} }$

$\sin(165) = \sqrt{ \frac{1 - \frac{ \sqrt{3} }{2} }{2} }$

$\sin(165) = \sqrt{ \frac{ \frac{2 - \sqrt{3} }{2} }{2} }$

$\sin(165) = \sqrt{ \frac{2 - \sqrt{3} }{4} }$

$\sin(165) = \frac{ \sqrt{2 - \sqrt{3} } }{2}$

How to make 4 3/8 in simplest form

SVEN [57.7K]

According to my knowledge, that mixed number already is in its simplest form. Turn it back into a fraction and it isn't divisible. A mixed number and 3 can't be divided perfectly by 8 or anything in common. So 4 3/8 is already in it's simplest form.
