Answer:
x = 65 degrees
Step-by-step explanation:
x° + x° + 50° = 180°
2x + 50° = 180°
2x = 180° - 50°
2x = 130°
x = 130°/2
x = 65°
If y⁸ is a function of x, that means that there cannot be more than one y value for each x value. You can test this by either doing the vertical line test, which requires you to graph the equation. To do this test, draw an imaginary vertical line anywhere on the graph. If the line crosses the curve at more than one place, it is not a function. Based on the graph (see below), this equation is a function of x.

If you want the answer it is 24.
You just plug it in.

If we are trying to figure out how long it takes for the tank to be fully drained, we just need to divide the volume of the tank by the rate at which oil is being drained.
We know the rate, so we need to find the volume of the tank.
Volume for a cylinder is pi * r^2 * h
Since the diameter is 1.6 ft, the radius is 0.8 ft. We know the length(height) and pi, so our expression for volume is:
3.14 * 0.8^2 * 4.5 = 9.0432 ft^3
Now we just need to divide volume by the drainage rate:
9.0432 / 1.9 = 4.75... ≈ 5 minutes
Hope this helps!
