The polygons are similar, but not necessarily drawn to scale. Find the value of x.

x = 9

Step-by-step explanation:

Since the two polygons are similar

16/12 = (x-1)/6

x = 9

i did it myself and i got 4.2 (b) hope its right

step-by-step explanation:

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
