[Right Triangles Only] Pythagorean Theorem: a² + b² = c²
- a is one leg
- b is another leg
- c is hypotenuse
Step-by-step explanation:
<u>Step 1: Identify Variables</u>
a = 19
b = <em>x</em>
c = 21
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute [PT]: 19² + x² = 21²
- Isolate <em>x</em> term: x² = 21² - 19²
- Exponents: x² = 441 - 361
- Subtract: x² = 80
- Isolate <em>x</em>: x = √80
- Simplify: x = 4√5
8 x 8 = 64
Each ‘face’ is 64in^2
64 x 6 = 384
= 384in^2
1 + 4 = 5 (5 parts)
<span>£250/5 = 50 </span>
<span>1 x £50 = 50 </span>
<span>4 x £50 = 200 </span>
<span>so the answer is 50:200 </span>
I round the answer to the second digit and get 18.33
My answer would be (0,5) because that seems to be where this scatter plot starts.
Hope this helps!
