So hmm checking the picture below
you can pretty much just use the pythagorean theorem to get the missing adjacent side

and just expand the sum identity with those values
5 hours because 20 divided by 4 is 5. 20 being the total hours.
Troy has a basis of $39 per share
total value of shares is $3900
