## Homework Statement

A line has direction angles 60°, 45°, 60° and passes through the point (1, -2, 5). Determine vector, parametric and symmetric equations of this line.

## Homework Equations

## The Attempt at a Solution

1/2 i + [root 2]/2 j +1 /2 k

parametric equation will be [1 ,-2, 5]

x= 1/2t+1

y=[root 2] /2 t+2

z=1/2 t+5

[x,y]= [1,2] + t[1/2,root2/2]

symmetrical

[x-1]/.5= {y-2]/[root2/2]}=[z-5]/.5

thats my final answer... please check if i have done it the proper way...
