If you have a unit circle, it means that you have a circle of radius r = 1 unit. So if we consider the scalene triangle of the figure, its vertical side is the sine of the theta angle and its horizontal side is the cosine of the theta angle. Then to find the hypotenuse of the triangle you use the Pythagorean theorem, thus relating the sine and cosine measures. I attach the solution.

Answer:

-3

Step-by-step explanation:

First you subtract the first equation from the second one and you get:

3x  + 3y   =  3

x +  y   =  1  

y =  1 - x

Then you use it on the first equation

888x  +  889 (1 - x)  =  890

888x  +  889  -  889x  =  890

-x = 1

x = -1

y = 1 - x

y = 1 - (-1) = 2

Now that you have those two numbers, we have to subtract the value of x from y:

x - y

-1 - 2 = -3

Hope this helps bro
