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 
No it is not. They are the wrong points
77 is the median score for rhis propblem
We can assume that the y-intercept for this equation is 125, because that would be how much Anna already has saved before she begins saving money from her allowance. Then, we know that Anna adds $2 to her savings each day from the problem, so we know that the slope will be positive 2 then.
Equation:
y = 2x + 125
