Hello guys, I got suspended from school and my asshole teacher sent me home a little quiz that is worth 200 points. The problem is, is that he taught this stuff when I was out. I told him that I wasn't there, but he doesnt care. So can anybody please help me with any of these problems??? Karma for all who helps!!!

w00t for trigonometry. Do you have a scientific calculator?

ok...so the ones that are marked with pencil, you've done. I won't do those.
b) tan y= 1.7601...that gives you 1.7601xtan-1 which results in 60.4o

I'm not going to help you, just a tip: you can use the sines law and/or pythagoras theorem

Its not too bad at all

Just remeber Sine Rule (a/sin a = b/sin b = c/sin c) and Cosine Rule (a^2 = b^2 + c^2 - 2bcCosA)

EDIT: Oh yes, where you have a right angle triangle (ie g and h) you can use c^2 = a^2 + b^2) and SOH CAH TOA

d) x=48

The others I really cannot be bothered doing.  Go here www.math.com
Scientific calc, help, equation solver...the lot.
Have fun.

Btw, is this not like...... 2nd year work?

d.) 2/3 x - 17/6 = 5/2
             + 17/6   +17/6
     2/3 x = 15/6 + 17/6
     2/3 x = 32/6
(3/2)2/3 x = 32/6 (3/2)

x = 8

How did you get that?
2/3x - 17 = 5/2 x 6
2/3x - 17 = 15
2/3x = 32
2x = 96
x = 48

d) 2/3 times x minus 17/6 = 5/2
so x(2/3)= 5/2 -(17/6)
x(2/3) =(15/6)-(17/6)
x(2/3)= -2/6
x(2/3)= -1/3
x= (-1/3) divided by 2/3
x= -1/2
No it's 8.  Plug it in.

by the way this is a cake walk. i'll set you up, but i won't finish them. you've heard of SOHCAHTOA right?
you may need to study a bit if you're running into trouble with this stuff.

D) first of all, add the 17/6 to 5/2 on the right side. divide by 2/3 to solve for x. this problem had nothing to do with trig.

G) sin 57 = 239/x

H) tan y = 36.8/22

2. draw a triangle. tan32.8 = x/40.

3. same triangle as (2). sin64 = x/65

1b) 1.0541
1d) 8
1g) 284.9748 feet
1h) 59.1279 degrees
2) 25.5614 feet
3) 58.4216 meters


I had them all worked out on some notebook paper and tried taking a pic, but only camera I have is a crappy phone camera. So here are the answers, if you still can't get it, I guess I could type it up in a word document or something...

It's 8.  Zimmer put 17 instead of 17/6
