Answer:
BA ≈ 1.88
General Formulas and Concepts:
<u>Pre-Algebra</u>
<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>
- Substitute [sine]: sin28° = BA/4
- Isolate <em>BA</em>: 4sin28° = BA
- Evaluate: 1.87789 = BA
- Rewrite: BA = 1.87789
- Round: BA ≈ 1.88
12-6+(14-8)2 = 18.
(12-6) + 2(6) =
6 + 12 = 18.
Okay my calculator now says it's 68.
Answer:
4 + x
Step-by-step explanation:
Given that :
Shortest side of tile (s) = 4 inches
Next shortest side (a) = x inches long
Longest side of tile (l ) =?
Since it is modeled in the form of a right angjed triangle ; then we can use Pythagoras rule ;
Length of longest side² = sum of the square of the two other sides
l² = 4² + x²
l² = 16 + x²
Take the square root of both sides
l = 4 + x
Hence, length of longest side = 4 + x
