Answer:
16
Step-by-step explanation:
The value of sin(2x) is 
Explanation:
Given that 
The formula for
is 
Since, 
Also, it is given that 
Thus,
and 
To find the hypotenuse, let us use the pythagoras theorem,

Now, we can find the value of sin x and cos x.


Now, substituting these values in the formula for sin 2x, we get,

Thus, the value of sin(2x) is 
Parentheses affect how equations are done.
EX. 1+1*4
4+1=5
VS
(1+1)*4
2*4=8
