If the supplement if an angle is 30 degrees more than the measure of the angle, what is the measure of the angle?

What is the binomial expansion of (2x-3)^5

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.

Plz hurry evaluate the expression a+b where a=8 and b=19
