What is the answer to this problem?

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

ian gonna lie that is way to much

the function makes a strait line horizontally with no x intercept but a y intercept at 9.
