Can anyone please explain why 7a) is 37 degrees?

It's been a while since I've done this sort of thing, but I don't believe $\bg_white \theta$ is $\bg_white 37^\circ$.

$\bg_white 37^\circ$ should be the angle between the east pointing line from Bourke and the line joining the two towns.

Then, $\bg_white \theta$ should be the complement of that, i.e. $\bg_white 90^\circ - 37^\circ = 53 ^\circ$.

Ok so I’m not a dumb fuck whose been wasting 4 days on this section, the answer in the book says 37 but I kept on getting 53

It is 53 degrees, the textbook has done 90+

=127 thus 37 being the answer which is incorrect.

Textbook is wrong. I think they thought by using alternate angles straight away, theta is 37. Definitely 53 degrees.
