10.
15.
20.
25.

Answer 1

(c) 20

Explanation:

Given similar triangles GYK and BAK, you want to find the value of x, where ...

GK = 10, GY = x, BK = 6, BA = 12

Similar triangles

Corresponding sides of similar triangles are proportional:

GY/GK = BA/BK

x/10 = 12/6

x = 10(12/6) = 20

The value of x is 20.
