Question

descubra o valor de x e y (teorema de tales )

Answer 1

A) x/10=10/8 > 8x = 10*10 > x= 100/8 > 12,5
    y/8=15/10 > y =  120/10 > y = 12

B) 2/3x = 3/4x+1 > 8x + 2 = 9x > 9x - 8x = 2 > x=2

C) 20 - 8 = 12
    8/12 = 10/x > 8x = 120 > x = 120/8 > X = 15

D) 10/4 = x+3 / x > 10x = 4x + 12 > 10x -4x = 12 > 6x = 12 > x=12/6 > x = 2
