I wanna say B but i don’t remember i had that question before though
The question doesn’t make much sense. Do you mean x=50-12? If so, x=38
Set up proportion 170/180=x/1 than cross multiply 170x=180 divide both sides by 170 answer 0.944 so 94% remains
<1, 1, 1> × <1, 0, 1> = <1, 0, -1>
The cross product of the normals of the planes gives the direction vector of their line of intersection.
