<u>Trigonometry</u>
[Right Triangles Only] Pythagorean Theorem: a² + b² = c²
- a is a leg
- b is another leg
- c is the hypotenuse<u>
</u>
Step-by-step explanation:
<u>Step 1: Define</u>
Leg <em>a</em> = 8
Leg <em>b</em> = 4
Hypotenuse <em>c</em> = <em>x</em>
<em />
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute in variables [Pythagorean Theorem]: 8² + 4² = x²
- Evaluate exponents: 64 + 16 = x²
- Add: 80 = x²
- [Equality Property] Square root both sides: √80 = x
- Rewrite: x = √80
- Simplify: x = 4√5
Answer:
A:
C -20 -15 -5
F(C) -4 5 23
Step-by-step explanation:
$36.8 because if you do 40 times .08 you get 3.2, after that you do 40-3.2 and you get 3.8. Hope this helps.
$72,00?
I'm assuming you are saying $7200, but if you are saying $72, just replace.
6% = 0.06
7200 / 0.06 = 432
So you would get $432. But trust me, no house is that cheap lol
