[Right Triangles Only] Pythagorean Theorem: a² + b² = c²
- a is a leg
- b is another leg
- c is the hypotenuse
Step-by-step explanation:
<u>Step 1: Identify</u>
Leg <em>a</em> = 8
Leg <em>b</em> = 6
Hypotenuse <em>c</em> = <em>x</em>
<em />
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute [PT]: 8² + 6² = x²
- Exponents: 64 + 36 = x²
- Add: 100 = x²
- Isolate <em>x</em>: 10 = x
- Rewrite: x = 10
Here is the solution on how much the total amount that Lisa paid:The total amount for all the items is $53: $10 + $20 + $23 = $53 Now, 7.2% = 0.072 Compute for the sales tax of each item:$10 x 0.072 = .72 $20 x 0.072 = 1.44 $23 x 0.072 = 1.66 The total sales tax would be: .72 + 1.44 + 1.66 = $3.82 Now add the Sales tax to the total price of the items. $53 + 3.82 = $56.82Therefore, Lisa paid $56.82.
