You can  put this solution on YOUR website! 12. angles VUW and XUT 
14. angles TYW and VXU (their sum is 90) 
16. angle XVU (what is UVZ + XVU?)
 
 
38. There are multiple pairs. Find pairs of consecutive angles that add up to 90 (for example, segments KA and KD because 20+25+45 = 90). 
40. Intersecting streets often form right angles, but other angles can be formed. You can sketch the streets (how am I supposed to do that online?). 
42. 4*5*6 = 2(10 + x), 120 = 2(10+x), 60 = 10 + x, x = 50.

Is there a part of the instruction "One problem per post" that you cannot comprehend?
