Question

find the x value in the given figure

Answer 1

Step-by-step explanation:

ang CAB = ang ABD (GIVEN)

ang AOC = ang DOB (VERTICALLY OPPOSITE ANGLES)

Therefore, by AA - criteria of similarity,

triangle AOC is similar to triangle BOD.

THEREFORE,

AC / DB = OC / OB

12 / 5 = 6 / x

x = 2.5
