Question

Use o teorema de Tales

Answer 1

b)
12 = x  → 12 . 6 = 2 . x → 72 = 2x → 72 = x → x = 36
 2    6                                              2

c)
   8      =  10  → 10 . (x + 1) = 8 . (x + 2) → 10x + 10 = 8x + 16 →
x + 1     x + 2                                                
continuando: 10x - 8x = 16 - 10 → 2x = 6 → x = 6 → x = 3
                                                                           2

d)
x = 9 → x . x = 9 . 4 → x² = 36 → x = √36 → x = 6
4   x
