Answer:
<h2>z = 27°</h2>
Because that angle is 30°.
it's nearest value is 27.
Use the change-of-basis identity,

to write

Use the product-to-sum identity,

to write

Redistribute the factors on the left side as

and simplify to

Now expand the right side:

Simplify and rewrite using the logarithm properties mentioned earlier.
