\(\frac{751}{1413}=0.53149327\dots \\ 0.53149327\times100=53.149327 \%\)

Answer 53 %

\(|\leftarrow\) it is module which is shows distance and it can t be negative

\(|-2+3|*5 \text{ (first do the module)}\\ |1|*5=5\)

A=atan(1.671) = 1.031521696125(radians) or 57,295779513224453(degree)

there s a bunch of the way to do that

what do you mean is my answer 37.5 is wrong ? (may be i did a calculation mistake :/  )

i think:

the hyp of the bigger triangle is devided into two parts  lets say one of them is "m" and the other is 'n'

so we can find m using pytha. theorem:

\(10^2-6^2=8^2\\ m=8\)

and there is a formula that:

\(a^2=m*(m+n)\\ a=10\\ m=8\\ 10^2=8*(8+n)\\ n=\frac92 \)

\(c=m+n\\ c=8+4.5=12.5\)

let s use again pyth. theorem:

\(12.5^2-10^2=7.5^2\\ b=7.5\)

\(A_{triangle}=\frac{7.5*10}{2}=37.5\)

another easier way to do that:

\(h^2=m*n\\ 6^2=8*n\\ n=\frac92\)

again :D

pi have infinitly number of digits

Thank you CPhill and Melody ! :)

no i don t even know what you are calling calculus
