$tt x = sqrt{ {6}^{2} - {3}^{2} }$

$tt x = sqrt{36 - 9}$

$tt x = sqrt{27}$

$tt x = 3 sqrt{3}$

$tt x = sqrt{ {8}^{2} + {4}^{2} }$

$tt x = sqrt{64 + 16}$

$tt x = sqrt{80}$

$tt x = 4 sqrt{5}$

Hitung lah segitiga nilai x

=========================================

b² = c² – a²

b² = 6^2 – 3^2

b² = 36 -9

b² = 25

b = 5

c² = a² + b²

c² = 4² + 8²

c² = 16 + 64

c² = 80

c² = 2√20

c² = 4√5
