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
Answer:
C
Step-by-step explanation:
Given the tables of H(t) an r(t), we want to find:

As stated, this is equivalent to:

Using the r(t) table, we can determine that:

Therefore:

And by using the H(t) table, we can determine that:

So, our answer is C.
