I have seen this question, or very similar ones, very recently.
\(\frac{(x+7)}{(x²-x-2)}+\frac{a}{x-2}+\frac{b}{(x+1)}\)
Such that what? Is there meant to be an equal sign somewhere?
I used sine rule followed by trig identities to get the value of sin
Then I used cosine rule to find the answer.
It was not an easy question.
I did not check my working but I also got an approx answer of 35.001.
Just do it on a calculator.

Well now you will know how to do it.
Thanks for the answer guest.
I would like to see too.
Maybe it would be in your interest to present your questions better.
All those unnecessary dollar signs make it difficult to read and I feel that if you cannot be bothered to present your question properly then it is not worth my effort to attempt to answer.
Hint:
From any arc of a circle, the angle subtended to the centre is twice that subtended to the circumference.
In this instance, the arc is minor arc BD
you can take if from there.
I copied
"Triangle WXY has side lengths XY = 14 and WX = 8. The tangent to the circumcircle of triangle WXY at X is drawn, and the line through W that is parallel to this tangent intersects XY at Z. Find YZ."
into the web2 search box, it took me to google and I found the page straight away.
