Answer:
z = 3/2 (turn it into decimal if required)
Step-by-step explanation:
Let the angle be x.
Taking x as reference angle
cosx = b/h
or, cosx= z/3
Again taking x as reference angle for the bigger triangle,
cosx = b/h
or, cosx = 3/6
or, cosx = 1/2
so, x = 60
Now,
As we found out,
cosx = z/3
or, cos60 = z/3
or, 1/2 = z/3
or, 3 =2z
so, z = 3/2
