Substitute for x in the second equation:-

2(y + 3) + y = 9

2y + 6 + y = 9

3y = 9 - 6 = 3

so y =  3/3  = 1

Now plug this value of y into first eqution:-

x = 1 + 3 = 4

So you answer is x = 4 and y = 1.

Find the missing side
Verdich [7]

Answer:

x=15.56

Step-by-step explanation:

We can use the law of sines here. However, we will first need to solve for the missing angle.

The interior angles of a triangle add up to 180.

Therefore,

35+90+x=180

where x is the missing angle.

35+90+x=180

x+125=180

x=55

So the missing angle is 55 degrees.

Now we can use the law of sines to set up a proportion.

\frac{19}{sin(90)}=\frac{x}{sin(55)}

Now simplify the equation.

x=15.56

<em>Rounded to the nearest hundredth.</em>
