so find hypotenuse \[h^2 = a^2 + b^2 \]

OpenStudy (jack1):

so find hypotenuse @mmholmes

OpenStudy (anonymous):

im not sure how.

OpenStudy (nurali):

\[d=\sqrt{(x _{_{1}}-x _{2})^2+(y _{1}-y _{2})^2}\] (1, -2) and (-4, 3) (x1,y1) and (x2,y2) x1=1 x2=-4 y1=-2 y2=3 \[d=\sqrt{(1+4)^2+(-2-3)^2}\] \[d=\sqrt{(5)^2+(-5)^2}\] \[d=\sqrt{50}\] \[d=5\sqrt{2}\]

OpenStudy (jack1):
