Treasure Hunt - Trigonometry - missing angles

Use this Treasure / Scavenger Hunt after teaching finding missing angles using trigonometry.
I have included all three trigonometric ratios (sine, cosine and tangent). There are a mixture of difficulty. Some questions are worded so students may need to draw a diagram first to help them

Instructions
Print off the twenty question pages and put them up around the room
Each question is in the middle of the page and the solution is at the top of another page.
Answers are correct to one decimal place where appropriate
A student begins on a given question, solves it and finds the answer on another sheet. The question on this sheet will be the next question they answer. Once they have answered all twenty, they will return to their starting question
Depending on numbers, students can all start on different questions
There is a student answer sheet included plus the correct sequence
