Using pythagoras' theorem u can find the length of the hypotenuse. a^2+b^2=c^2 Here a=2, b=3, c=? dw:1362407511223:dwdw:1362407540894:dw Does that help? @Atkinsoha

I did all of that.. I'm stuck on maybe how to solve it, since I can't seem to come up with any of the answers that are given.

That's were I'm lost apparently. 3^2 = 9 and the (√13)^2 = 13?

WAIT. Is it A? 5/13? because then it would be 2(9/13)1 which would be (18/13)1 and one would be 13/13 so it would be 5/13? A?

let us say arcsinx=theta nd arccosx=beta so sin theta=x nd cos beta =x sin(arcsinx+arccosx)=sin(theta+beta) =sin theta*cos beta+sin beta * cos theta

cos theta=sqrt(1sin^2theta) sin beta=sqrt(1cos^2 beta) plug in the values and u will get the algebraic expression:)
