Answer:

The volume of the steps is:

  • <u>324,000 cm3</u>

Step-by-step explanation:

Remember that the volume regularly is:

  • Volume = height * width * depth.

There are many forms to solve this exercise, but I'll show you two:

1. Imagine that aren't steps but a big solid, then its volume would be:

  • Volume of big solid = 60 cm * 60 cm * 120 cm
  • Volume of big solid = 432000 cm3

Now you can subtract the volume of a small solid with measures 30 cm * 30 cm * 120 cm (<em>where is the blank for the step</em>):

  • Volume of a small solid = 30 cm * 30 cm * 120 cm
  • Volume of a small solid = 108000 cm3

Now you subtract:

  • Volume of the building steps = 432000 cm3 - 108000 cm3
  • <u>Volume of the building steps = 324000 cm3 </u>

2. The building steps are formed by three solid with volume 30 cm * 30 cm * 120 cm, so:

  • Volume of the building steps = 3 (30 cm * 30 cm * 120 cm)
  • <u>Volume of the building steps = 324000 cm3</u>

Fill in Sin, Cos, and tan ratio for angle x. <br> Sin X = 4/5 (28/35 simplified)
Fantom [35]

Answer:

Given: \sin(x) = (4/5).

Assuming that 0 < x < 90^{\circ}, \cos(x) = (3/5) while \tan(x) = (4/3).

Step-by-step explanation:

By the Pythagorean identity \sin^{2}(x) + \cos^{2}(x) = 1.

Assuming that 0 < x < 90^{\circ}, 0 < \cos(x) < 1.

Rearrange the Pythagorean identity to find an expression for \cos(x).

\cos^{2}(x) = 1 - \sin^{2}(x).

Given that 0 < \cos(x) < 1:

\begin{aligned} &\cos(x) \\ &= \sqrt{1 - \sin^{2}(x)} \\ &= \sqrt{1 - \left(\frac{4}{5}\right)^{2}} \\ &= \sqrt{1 - \frac{16}{25}} \\ &= \frac{3}{5}\end{aligned}.

Hence, \tan(x) would be:

\begin{aligned}& \tan(x) \\ &= \frac{\sin(x)}{\cos(x)} \\ &= \frac{(4/5)}{(3/5)} \\ &= \frac{4}{3}\end{aligned}.
