After walking 11 km due north from camp, a hiker then walks 11 km due east. what is the total distance walked by the hiker? dete
rmine the total displacement from the starting point.
1 answer:
You should know the difference between the displacement and the distance. The distance is the length traveled all throughout the path covered. The displacement is the length traveled from the starting point to the final point. In this case, the distance is
Distance = 11 km + 11 km = 22 km
In the diagram, the red line is the path for the displacement. By pythagorean theorem, the solution is
Displacement = √11² + 11² = 15.56 km
Distance = 11 km + 11 km = 22 km
In the diagram, the red line is the path for the displacement. By pythagorean theorem, the solution is
Displacement = √11² + 11² = 15.56 km

<h3>Answer: XWY and STR</h3>
I tend to think of parallel lines as train tracks (the metal rail part anyway). Inside the train tracks is the interior region, while outside the train tracks is the exterior region. Alternate exterior angles are found here. Specifically they are angles that are on opposite or alternate sides of the transversal cut.
Both pairs of alternate exterior angles are shown in the diagram below. They are color coded to help show how they pair up and which are congruent.
A thing to notice: choices B, C, and D all have point W as the vertex of the angles. This means that the angles somehow touch or are adjacent in some way due to this shared vertex point. However, alternate exterior angles never touch because parallel lines never do so either. We can rule out choices B,C,D from this reasoning alone. We cannot have both alternate exterior angles on the same exterior side of the train tracks. Both sides must be accounted for.
