Answer:
14) x = 30°
15) x = 50°
Step-by-step explanation:
14) 60 + x = 90
      x = 90 - 60
      x = 30°
15) 130 + x = 180
      x = 180 - 130 
      x = 50°

Supposing, for the sake of illustration, that the mean is 31.2 and the std. dev. is 1.9.
This probability can be calculated by finding z-scores and their corresponding areas under the std. normal curve.  
                                                                     34 in - 31.2 in
The area under this curve to the left of z = -------------------- = 1.47 (for 34 in)
                                                                           1.9
                                                                      32 in - 31.2 in
and that to the left of 32 in   is               z = ---------------------- = 0.421
                                                                             1.9
Know how to use a table of z-scores to find these two areas?  If not, let me know and I'll go over that with you.
My TI-83 calculator provided the following result:
normalcdf(32, 34, 31.2, 1.9) = 0.267  (answer to this sample problem)
