Question

Determine o valor De X

Answer 1

A)
 
x² = 3² + 4²
x² = 9 + 16
x² = 25
x = $\sqrt{25}$
x = 5

B)   

x² = 5² + 12²
x² = 25 + 144
x² = 169
x = $\sqrt{169}$
x = 13

C)

10² = 6² + x²
100 = 36 + x²
64 = x²
$\sqrt{64}$ = x
x = 8

D)

15² = 12² + x²
169 = 144 + x²
25 = x²
x = $\sqrt{25}$
x = 5
