What are the values of x and y

Its the last choice.

Step-by-step explanation:

Triangles ADB and BDC are similar, so

8/15 = x / 8

15x = 64

x = 64/15.

y/17 =  x / 8

y/17 = 64/15  / 8

y/17 = 8/15

15y = 8*17

y = 136/15.

the 4 th option

Step-by-step explanation:

Δ DAB and Δ DBC are similar triangles thus the ratios of corresponding sides are equal, that is

= , substitute values

= ( cross- multiply )

15x = 64 ( divide both sides by 15 )

x  =

--------------------------------------------------

and

= , substitute values

= ( cross- multiply )

15y = 136 ( divide both sides by 15 )

y =

b

step-by-step explanation:

b

2 and 1.

step-by-step explanation:

plug in each answer. 0 doesn't work, 1 does. so does 2. 4 doesn't:

0 = 1 is not true.

2 = 2 is true.

4 = 4 is true.

8 = 16 is not true.

hope this !
