Lisa hases a treehowz. Her treehowz has a 28-yard rope tied to it and makes a 37 degree angle with the ground. Find the height.

What is the direction of the vector (7,2)?

cos (5 pi/6)?

A train is flying at 75 mph, 110 degrees from the north. There is a wind blowing east at 20 mph. Find the speed of the train due to the wind.

What is the train's new direction?

sin^2 x +cos^2 x=?

convert (3, 7 pi/4) into cartesian coordinates.

convert (-6, 2) into polar coordinates.

Moar Treehowzes! The height is 30 ft, the rope is 65 ft, and the rope is attached to the ground 40 ft from the base. (the treehowz isn't nessisarily upright). Find the rope's angle
