Looks like the answer is 72.89 degrees, which is roughly equal to 73 degrees.
First, divide 17 by 5. You will get 0.2941176470588235. Now take the inverse cosine (cos^-1) of that decimal (0.2941176470588235). The raw answer is 72.895364823356 degrees, and the rounded answer is 73 degrees. Hope this helps.
