    30 is the result of calculating \(\Large \frac{1}{2}(80-20)\).

    1/2(158-64) =47 is alright. But that's not the final answer. I think you need to solve for x, even though you did not post the question. To do that, equate that angle 9x-5 to 47 and solve for x.

    so 47=9x+5

    I think I read 9x-5. Perhaps I need glasses!

    You're very close, probably just a rounding problem. To round a decimal number, to 2 places of decimal, you would round up if the third digit after the decimal is greater than or equal to 5, or truncate if the third decimal is 4 or less.
