Parametric form of a circle is x = h + r cos t, y = k + r sin t where (h , k) is coordinates of the center of the circle. r is the radius
so for this circle the equations are
x = 1 + 3 cos t and y = 2 + sin t

Let the height of the flagpole be x, then
tan 30 = x/75
x = 75tan 30 = 43 feet
Therefore, the height of the flagpole is 43 feet.
Percy used to have 100% of the shirts (before he started selling them). Since then, he has given away 90% of the shirts and is now left with only 10% of what he used to have. He currently has 25 shirts, meaning that 25 is 10% of what he had.
Lets set up a proportion:
25 shirts : 10%
x shirts : 100%
x = 25*100 / 10
x = 2500 / 10
x = 250 shirts
Percy started off with 250 shirts.
