Thanks, I appreciate it! Glad it was helpful
for question 1c should i use radian or degrees?

For 1c, since the angle is given in degrees, it would be best to keep it in degrees - don't need to convert this to radians first.

@@MLPBMathematics-cp4tn alright, just making sure since I think you used radians in the video

@@Mini5hrek Oh wow, good catch - see now the calculator changes to radians after the screen was cleared. Using degrees, final answer should be 8.75m for this one. Thanks!
Where do you find the mark scheme for this?
