I think we're not supposed to do more than 3 problems in one answer; certainly not five pages. Does the 1/3 mean there are 10 more to come?

I'll do the first page.

Right triangle, opposite side of 10, adjacent side of 21,

tan x = opp/adj = 10/21

x = arctan 10/21 = 25.46°

Answer: 25

cos x = adj / hyp = 10/14

x = arccos 10/14 = 44.42°

Answer: 44

tan x = opp/adj = 12/24 = 1/2

x = arctan 1/2 = 26.57°

Answer: 27

tan x = 31/32

x = arctan 31/32 = 44.09°

Answer: 44

Mrs. Mitchell decided to grade her projects by giving each student 50 points if they turned in a project and then an additional

photoshop1234 [79]

Let $c$ be the amount of parts the student answered correctly. Suppose that $s(c)$ is a function between $c$ and the score of a student's project. As the student initially receives a fixed $50$ points for turning the project in and $5$ points for each correct part, the function is initially:

$s(c) = 5c+50$

When the students receive $7$ points for each correct part, the coefficient of $c$ changes, as the amount of points received per correct answer increases. Thus:

$s(c) = 7c+50$ .
