on a blueprint a square with 20 meters per side was shown as a square with 12 centimeters per side. How long would a girder appear on the blueprint if the girder is actually 15 meters long?

Two parallel lines are crossed by a transversal. what is value of x

Bring the fraction a/a-4 to a denominator of 16-a^2

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.
