If you have a calculator I would suggest using that, but otherwise here's the process:
170
+130
--------
Add the zeros.
0
+0
-----
Add 70 and 30.
70
+30
------
Carry the 1 on the 10
Add 100, 100, and 100 (From the 10)
100
100
+100
--------
Add 300, 0, and 0.
300
0
+ 0
---------
The answer is 300.

x=2 is the perpendicular bisector of segment UU'.
Answer:
116 degrees
Explanation:
If we divide the triangle from the vertex of the triangle, the vertex angle of each triangle would lie on a straight line in the triangle. Angle on a straight line is 180 degrees.
If the vertex angle of one triangle is 64 degrees then the vertex angle x of the other triangle is 180 degrees - 64 degrees = 116 degrees.
