This is so hold up

Just in case somebody cares: The Maths behind it is something along the lines of
180°-[360°-(100°+120°+60°)]

Spoiler

=100°

One of the very rare RARE cases of an actual math question being asked in a manga or anime. Usually it's just "how do I do this?" and the reply is "you do this and that" and that's it.

She has got some serious charm that is for sure

 

[KipTheGamer]

Nice.

 

[manabi]

How could anyone tell her no with that expression?

 

[bahamutmybitch]

sheesh

 

[ieatass69]

no way an elementary schooler has to learn about angles

 

[Maes]

@ieatass69 Exactly, I wonder if it was a mistake and she's at actually middle schooler

I'm not sure if the author can do basic math. It's true that all 4 sided shapes have angles that add up 360 degrees and that 120 and 60 adds up to 180, but the right angle labeled 100 degrees should say 90 because all right angles are 90 degrees. So the bottom angle not shown should be 90 degrees for 2 reasons, first the missing angle is also drawn as a right angle, second the other angles 120 and 60 add up to 180 and all angles must add up to 360 so, 360 - 180 - 90 = 90. it's not hard, it's elementary school math.

side note: if that mislabel right angle was really 100 then the missing angle would have been 80. 360 - 180 - 100 = 80
