Answer 1

theres a thrm we could use, that i never remember; or we could hack this thing up into a thrm I do recall :)

Answer 2

this mouse aint good for that

Answer 3

ideally; the angle I created is half the outer arc length; the supplement to it is 180- n/2

knowing 2 angles of a triangle we can determine the third

Answer 4

180-(a+180-n/2) would be the third angle out there

and since the arc we are looking for is subtended by it we just double the results

Answer 5

98 and 27 ....

2(180-(27+(180-98/2)))

is my guess
