What is the value of u

U=31

The exterior angles of any polygon always add up to 360 degrees.
You can add all the sides and combine like terms, then solve for u.
5u-46+u+1+u+9+u+49+3u-27+u+2 = 360
12u-12=360
12u=372
u=31

Where the white dots are is where your points should be plotted.a translation is simply just moving something from one place to another. in this case, you would move each plot point of the original shape 2 units up, and 5 units to the left.
