Answer:

The height of water in the container is 5 cm

Step-by-step explanation:

Here, we want to calculate the height of the water in the container

Mathematically, the volume is :

50 * 30 * h = 1500h cm^3

Also, 7.5 L = 7500 cm^3 = 7.5 L

Let the height be h

1500h = 7500

h = 7500/1500

h = 5 cm

Answer: 66 degrees

Explanation:

Check out the attached image below. Figure 1 is the original image without any additions or alterations. Then in figure 2, I extend segment BC to form a line going infinitely in both directions. This line crosses segment DE at point F as shown in the second figure.

Note how angles ABC and DFC are alternate interior angles. Because AB is parallel to DE (given by the arrow markers) this means angle DFC is also 24 degrees

Focus on triangle DFC. This is a right triangle. The 90 degree angle is at C.

So we know that the acute angles x and 24 are complementary. They add to 90. Solve for x

x+24 = 90

x+24-24 = 90-24

x = 66

That is why angle CDE is 66 degrees
