@segarrogers.bsky.socialI think the maths historians would probably call this a 'surveyors' problem. Am in the process of making a sheet of them ... unless anyone already has such a thing.
(The 40 and the 72 are the areas of the rectangles formed by the respective diagonals).

@segarrogers.bsky.socialAn idea for a question:
Without recourse to calculators, tables or graphing packages:
a) Place sec x, cos x, tan x, cot x, csc x & sin x in order, from smallest to largest, when x = 1°.
b) How is this different for x = 44° ?

@ridermeister.bsky.socialAnother early question for new Year 12 FM pupils. This one is intended to show them that mathematics (at A-Level) doesn't really have 'hard' topics, we can make it all 'hard'!
