An Oriented Bounding Box (OBB) is centred at (3,1) with half-extents of (3, 1.75) and is oriented at
an angle of 25 degrees.
In the table below write down the positions of each of the vertices which make up the OBB.
Give all answers to 2 decimal places.
Been given this question could some one please show me the answer and working out thankyou !

Alas, no, as this is an assessment homework.
Remember that you can use sine, cosine, and tangent to manage angles. Each corner of your rectangle is an (x,y) point relative to the origin (or center) of your rectangle.
Theta is the angle at the center of your rectangle. Find the angle when the rectangle is not rotated, then add the rotation (25 degrees -- don't forget to convert to radians) to the angle, then go back and calculate the new (x,y) position of the corner.
Good luck!

Duoas just answered your question and all you do is give back a load of sarcasm and misspelling? What an arse.
