Answer:

BA ≈ 1.88

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Equality Properties

<u>Trigonometry</u>

  • [Right Triangle Trig] sin∅ = opposite over hypotenuse

Step-by-step explanation:

<u>Step 1: Define</u>

We are given a right triangle. We can use trig to find the missing length

<u>Step 2: Identify Variables</u>

<em>POV from angle C</em>

Angle = 28°

Adjacent = BA

Hypotenuse = 4

<u>Step 3: Solve for </u><em><u>BA</u></em>

  1. Substitute [sine]:                     sin28° = BA/4
  2. Isolate <em>BA</em>:                               4sin28° = BA
  3. Evaluate:                                  1.87789 = BA
  4. Rewrite:                                   BA = 1.87789
  5. Round:                                     BA ≈ 1.88

Is it possible to get a volume of 12000 cm3 with a surface area between 3200 cm3 and 4000 cm2?
jenyasd209 [6]
You can try with : 30 x 40 x 10.  Volume is 12000 and the surface area:
2*30*40 + 2*30*10 + 2*40*10 = 2400 + 600 + 800 = 3800. This is a surface area between 3200 cm² and 4000 cm².
