The coordinates of the vertices of △ABC are A(1, 4), B(−2, −1), and C(−3, −2). The height h to side BC is 2, and b is the length of BC. What is the area of △ABC? The area of △ABC is

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.
