The base of a regular pyramid is a hexagon. what is the area of the base of the pyramid? (express your answer in radical form)

1. what is the measure of ∠abc? what is the measure of ∠abd?

He that is measured at 220° is a reflex angle. the opposite angle is obtuse. find the measure of obtuse .

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.
