Suppose that you have a square pyramid like the one pictured. Which plane section will produce a triangle? A)

A cut parallel to the vertical axis, but off the vertical axis

B)

A cross section cut parallel with the bottom

C)

A cut parallel to the vertical axis, directly through the vertical axis

D)

Cutting off one of the bottom corners

In triangle △abc, ∠abc=90°, bh is an altitude. find the missing lengths. ah=4 and hc=1, find bh.

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.
