Answer: C
combine 49 and 28 and subtract form 180 getting 103 then you get the vertical number straight down.
C.x+49+28=180. Explanation:the top angle and the bottom angles are same so........ 49+28=77. 180-77=103°
ASSUMPTION: Since we are talking about fractions it looks like you have to simplify it. Again, its still a guess so Id assume..
16/12 = 4/3.. So It should be <em>h = 2 </em>
