One angle of a triangle has a measure of 66. the measure of the third angle is 57 more than 1/2 the measure of the second angle. the sum of the angle measures of a triangle is 180. what is the measure of the second angle? what is the measure of the third angle?

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.
