I hated pictures like this in school. The numbers are just slapped on an inaccurate image and somehow they expect people to ignore the obvious right triangles and just focus on the math part of it.
If it was to scale you could just use a protractor and skip the whole math part, which is the entire part of the lesson…
I don’t see that as a downside as long as these two questions are also included.
How many degrees make up the inner angles of a triangle?
How many degrees make up one side of a straight line?
Big assumption that the bottom line is straight / not two lines connecting at a different angle
And what’s wrong with that. Utilizing real world solutions to problems is a life skill. Not some obscure formula that you will forget anyway.
If the student eventually does geometry for money, they’ll discover that customer CAD files invariably have some bizarre error like this.
I was scared I forgot basic trig stuff.
I love that every comment focus on the math puzzle. Since the other stuff is clearly uninteresting.
