Step-by-step explanation:
To solve this question I would use the sin rule.
The sin rule states that

Therefore if you substitute in your numbers you get:

If you rearrange that you get:

Therefore a = 17.3 Inches (to 3 sf)
This can also be done with basic trigonometry where you would get

Rearranging to

meaning the answer is 13.7 inches
Use a z-test where z=(xbar-mean)/sigma/sqrt(n)
The denominator is the SE and is 1.6/sqrt(30)=0.292
z=-0.5/0.292 and .9/.292 or between -1.71 and 3.08
that probability is 0.9553.
