- Pythagorean Theorem: a² + b² = c²
Step-by-step explanation:
<u>Step 1: Define</u>
Leg <em>a</em> = <em>x</em>
Leg <em>b</em> = 7
Hypotenuse <em>c</em> = 10
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute: x² + 7² = 10²
- Isolate <em>x</em> term: x² = 10² - 7²
- Exponents: x² = 100 - 49
- Subtract: x² = 51
- Isolate <em>x</em>: x = √51
The length of the missing leg is 11.31
<h3>Pythagorean theorem formula</h3>
a² + b² = c²
<em>While</em><em> </em><em>c</em><em> </em><em>is</em><em> </em><em>the</em><em> </em><em>hypotenu</em><em>se</em><em> </em><em>part</em><em>.</em>
<h3>Known</h3>
a = 4
b = ..?
c = 12
<h3>Way to do</h3>
a² + b² = c²
4² + b² = 12²
16 + b² = 144
b² = 144 - 16
b² = 128
b = √128
b = 11.3137085
#nearest hundreth (2 decimal places)
b = 11.31

24% = 0.24
multiply that by the price:
800 * 0.24 = 192 ( discount)
800-192 = $608 sale price

Answer:
4 X 3 = 12 , 12 X 2 = 24
5 X 4 = 20, 20 X 2 = 40
3 X 5 = 15, 15 X 2 = 30
30 + 40 + 24 = 94 cm squared
