Question

The value of 6sin20degrees - 8sincube20degrees​

Answer 1

Answer:

1. 3577jdegres 224554gm the same time

Answer 2

Answer:

√3

Step-by-step explanation:

We know that,

If x is a given angle then

$\sin(3x) = 3 \sin(x) - 4 { \((sin(x)) }^{3}$

To solve the question, put x=20°

Then,

Sin(60°)= 3sin(20°) - 4(sin20)^3

Therefore, value of required equation is

2[3sin(20)-4sincube20]

=2[Sin(60°]

=2((√3)/2)

=√3

Therefore, the value of the expression is √3
