Pythagoras

Pythagoras adalah bilangan yang kuadrat bilangan terbesarnya sama dengan jumlah kuadrat bilangan lainnya.

[tex]\boxed{a^{2} =b^{2} + c^{2}} \:\:atau\:\:\boxed{a=\sqrt{b^{2} + c^{2}} }[/tex]

1.)  x = √(9² + 12²) = √(81 + 144) = √225 = 15

y = √(x² + 18²) = √(15² + 18²) = √(225 + 324) = √549 = 3√61

2.)  x = √(10² - 6²) = √(100 - 36) = √64 = 8

y = √(17² - x²) = √(289 - 64) = √225 = 15

3.)  x = √(41² - 9²) = √(1681 - 81) = √1600 = 40

y = √(30² + x²) = √(900 + 1600) = √2500 = 50

4.)  x = √(25² - 7²) = √(625 - 49) = √576 = 24

y = √(26² - (x - 14)²) = √(26² - (24 - 14)²) = √(676 - 100) = √576 = 24

Answer 2

1) x = √9² + 12²

= √(9(9) + (12(12)

= √81 + 144

= √225

= √15²

= 15

Y = √15² + 18²

= √(15(15) + (18(18)

= √225 + 324

= √549

= √9.61

= √3².61

= 3√61

2) X = √10² - 6²

= √(10(10) - (6(6)

= √100 - 36

= √64

= √8²

= 8

Y = √17² - 8²

= √(17(17) - (8(8)

= √289 - 64

= √225

= √15²

= 15

3) X = √41² - 9²

= √(41(41) - (9(9)

= √1.681 - 81

= √1.600

= √40²

= 40

Y = √30² + 40²

= √(30(30) + (40(40)

= √900 + 1.600

= √2.500

= √50²

= 50

4) X = √25² - 7²

= √(25(25) - (7(7)

= √625 - 49

= √576

= √24²

= 24

Y = √26² - (24 - 14)²

= √(26(26) - 10²

= √676 - (10(10)

= √676 - 100

= √576

= √24²

= 24
