## Homework Statement

At what point do the curves r1(t) = (t, 4-t, 63+t^2) and r2(s)= (9-s, s-5, s^2) intersect?

Answer in the form: (x,y,z) = ____

Find the angle of intersection theta to the nearest degree.

## Homework Equations

## The Attempt at a Solution

i: t=9-s

j: 4-t=s-5

k: 63+t^2=s^2

i/j: t-9s

k: 63+(9-s)^2=s^2

"Solving for "s""

s=8

t=1

I know not what to do from here. :-(
