Which of the following steps is included in the construction of a perpendicular line through a point off the line? Connect arcs above the line with arcs below the given line with a straightedge.
Connect arcs that are either above or below the original line and a point off the line with a straightedge.
Create arcs on either side of a point that is off the given line.
Create a copied angle by using the first two lines as the original angle.

:24% of students in a class are girls. if there are less than 30 students in this class, how many students are there? how many girls are there?

In each of the cases that follow, the magnitude of a vector is given along with the counterclockwise angle it makes with the +x axis. use trigonometry to find the x and y components of the vector. also, sketch each vector approximately to scale to see if your calculated answers seem reasonable. (a) 50.0 n at 60.0°, (b) 75 m/ s at 5π/ 6 rad, (c) 254 lb at 325°, (d) 69 km at 1.1π rad.

On traditional maps, earth is represented in a flat plane, or by euclidean geometry. however, a globe is a more accurate model that comes from elliptical geometry.how does a globe represent the fact that there are no parallel lines in elliptical geometry? the equator is not parallel to any other latitudinal lines. the north and south poles are never connected by a geodesic. the geodesics connecting the north and south poles never intersect. the geodesics connecting the north and south poles intersect at both of the poles.
