**Answer:**

I don't see how to answer this. What graph?

**Step-by-step explanation:**

Answer: x = 33 degrees

Step-by-step explanation:

The given triangle is a right angle triangle.

From the given right angle triangle,

The length of the hypotenuse of the right angle triangle is 19

With x degrees as the reference angle,

The length of the adjacent side of the right angle triangle is 16

To determine x, we would apply trigonometric ratio

Cos θ = adjacent side/hypotenuse side. Therefore,

Cos x = 16/19 = 0.842

x = Cos^-1(0.842)

x = 33 degrees

-- If the average of 4 numbers is 8, then they must all add up to 32 .

-- If 3 of them add up to 22, then the 4th number is **10** .

-2(5y - 1) - y = -4(y - 3)

- 10y + 2 - y = -4y + 12

- 11y + 2 = -4y + 12

-7y = 10

y = -10/7

** y = - 1 3/7**
