Answer:

the 4 th option

Explanation:

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


(DA)/(DB ) =
(DB)/(DC), substitute values


(15)/(8) =
(8)/(x) ( cross- multiply )

15x = 64 ( divide both sides by 15 )

x =
(64)/(15)

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

and


(DA)/(DB) =
(AB)/(BC), substitute values


(15)/(8) =
(17)/(y) ( cross- multiply )

15y = 136 ( divide both sides by 15 )

y =
(136)/(15)

Answer:

Its the last choice.

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.
