A. Write a two-column proof.
Given: AB is congruent to CD
Prove: AC is congruent to BD

This is so harddd! solve. 1 + 1 = solve 4 + 4 = solve 3 x 3

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.

Which equation represents the function on the graph?
