Answer:

x = 12.5

Explanation:

The large outer triangle and the small inner triangle are similar, thus the ratio of their corresponding sides are equal, that is


(20)/(6x-7) =
(15)/(15+36) =
(15)/(51) ( cross- multiply )

15(6x - 7) = 1020 ( divide both sides by 15 )

6x - 7 = 68 ( add 7 to both sides )

6x = 75 ( divide both sides by 6 )

x = 12.5
