After a dilation, triangle A (0,0), B (0,4), C (6,0) becomes triangle A' (0,0), B' (0,10), C' (15,0). Choose the scale factor for this dilation. *please help!*

a28=58

step-by-step explanation:

a1=a1+(n-1)d

a28= 4+ (28-1)2

a28=4+(27)(2)

a28=4+54

a28=58

1. supplementary angles

2. acd and bcd

step-by-step explanation:

step by step solution :

step   1   :

1.1     4 = 22

(4)3 = (22)3 = 26

equation at the end of step   1   :

  ((23) • 26)2

step   2   :

equation at the end of step   2   :

  (23 • 26)2

step   3   :

final result :

  218
