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.
Fun fact: In Turkey's university admittance exam, all angles have to be absolutely accurate, and measurements have to be scaled down perfectly to the visible shape in a geometry question.
To what tolerance, though? Writing math exams has now become an engineering problem.
If it was to scale you could just use a protractor and skip the whole math part, which is the entire part of the lessonβ¦
Then they could use decimals so it's unlikely to get it right without calculating, 60.17Β°, 40.29Β°, 35.43Β°
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 whatβs wrong with that. Utilizing real world solutions to problems is a life skill. Not some obscure formula that you will forget anyway.
Adding and subtracting is a real life solution. Not sure how that is "obscure"
You are being obtuse. You know what I mean by obscure.
Its intended to focus on a specific skill, the other skill can be valid and not be the point of the lesson.
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.
