Answer:
This question confused the heck out of me, but I tried my hardest. Here you go:
Step-by-step explanation:
I solved the problem with sin and cos and all that, and I got 2.81859485365.
When I divided pi by 2, I got 1.57079632679
. So basically, the problem that was supposed to show that 0<C<pi/2 is correct is incorrect. Does that make sense? If not, just ask in the comments, and I'll edit this answer.

Answer:
Step-by-step explanation:
Answer:
There are 14 4-point questions and 26 2-point questions.
Step-by-step explanation:
m = number of 4-point questions
n = number of 2-point questions
m+n =40
4m + 2n =108
You can solve system by elimination:
Multiply the 1st equation by -4 and keep the 2nd equation the same.
−4(m+n=40) → -4m -4n= -160
4m+2n=108 add them up
-2n = -52 divide both sides by -2
n = 26
plug it back in to solve for m
m + n = 40 →m + 26 =40 subtract 26 to both sides
m = 14
