So much for my dreams at being a fucking engineer.

Oh well, i could always be an english teacher. Requierments on puertorico aren't THAT high to be exact.

So any ways, i have bitch ass trigonometry homework.

And due to certain cases, my math skillz droped to that of a 7th grader.

so i'm here for help <3

i need the answers to well. all of them : ( this is part on, the shortest one.
I have afterwards 4 more parts made up of 20+ questions, so i'd find it a huge help if you'd help me with part 1 >.> the easiest one.

i'll be using * as my mark for degrees later on, sorry about that.

NOTE, i have 2 weeks to finish : ( it's worth a whole damn grade >.>


so anyways.

1. using exact values, verify that cos 60 (degrees) = 1 - 2 sin (root) 30 (degrees)

2. using exact values, find the value of:

A. 12 sin 30(degrees) - 6 tan 45 (degrees) + sec 45(degrees)/52

B. sin 2A+tan 3A/2 - cos A + sec (A+15 degrees), when A=30 ( degrees)

3. write the other functions of x if cos x= 3/5

4. In a right triangle sin A= 3/4 and C= 17. find A and B.

Be sure to draw a right triangle and letter it properly.

5. Find the following functions correct to five decimal places:

A. sin 22* 43'
B. cos 44* 56'
C. sin 49* 17'
D. tan 11* 37'
E. sin 79* 23' 30''
F. cot 19* 0' 25''
G. tan 64* 6' 45''
H. cos 29* 45' 48''
I. cot 78* 45' 48''
J. cos 15* 12' 51''

6. Find the acute angle A to the nearest second when.

A. sin A= 0.30985
B. cot A= 0.52613
C. cos A= 0.77273
D. tan A= 6.63831
E. sin A= 0.10655
F. cos A= 0.55570
G. sin A= 0.92112
H. tan A= 0.13476
I. cot A= 0.32323
J. cos A= 0.75273

7. The vertex angle of an isosceles triangle is 57* 24' and each o fit's equal sides is 375.5 ft long. Find the altitude of the triangle

8. Solve the follow right triangles:

A. a=117 ft, b= 16.35 ft
B. b=8* 29', a= 32.8 FT

9. A man standing on top of a building sees an automobile on a street below him. The angle of depression is 36* 22'. If his eye is 550 ft above the level of the automobile, how far is the automobile from him?

10. when the sun's angle of elevation is 30* the shadow of a post is 6 ft longer than when the angle is 45*. find the height of the post.

11. In a right triangle, given a=32.8 FT and A= 28* 30' 15''.
solve for B and C.

That's part 1. part 2-5 i'll answer my self ( i hope )

parts 2-5 include 20-45 questions per part.......oh lord.

So i'd be beyond grateful if you would help me with part 1 : (
I just gave up my dream at being anything better then a Mc Donalds worker.
