Find h, assuming the triangles formed are similar.

h =

Here is your answer

h= 15

REASON :

Since triangles formed are similar,

so its corresponding sides are proportional.

i.e. 6/h= 8/20

On solving we get,

h= 6/8 ×20

h= 120/8

h= 15

HOPE IT IS USEFUL

the solution is h=10 because you add 9 to each side of the equation.
