Question

x = , y =

Answer 1

this uses pythagorean's theorem

For all 90degree triangles we know that \[side1^{2} + side2^{2} = hypotenuse^{2}\]

so

\[5^{2} = y^{2} + (3+x)^{2}\]

from there, just seperate the variables so x is on one side and y is on one side and solve for each

Answer 2

i got X is 4 is that right?

Answer 3

umm.. are you there....

Answer 4

so that mean 25=y(sq2)+9
