What is the value of x if m ∠ 5 = 10x + 5 and m ∠ 3 = 8x - 5

15 points ! ~ see if you know the answer to both you!

How do the definitions, properties, and postulates you've learned about line segments, parallel lines, and angles to define the shapes of polygons

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.
