Evaluate the following expression [(15+1)/2-4]*6

Are triangles the congruent? write the congruency statement. what is the congruency that proves they are congruent? what is the perimeter of ∆pqr?

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.

On a piece of paper, graph y< x-1. then determine which answer choicematches the graph you drew.13. z3. 2(3.290-1)
