[URGENT DUE 30th APRIL] Advanced maths

If anybody could help me out with the following..
I will worship you for a week lol...


But honestly - I have no idea what to due, and its due in tomorow.

ALL help appreciated lol!
thanks for looking!

 

I'm only in geometry, so I only know the answer to number three. The answer would be the angle opposite the hypotenuse, which is the 12 inch side.

 

but how to work out the angle EXACTLY?

other than drawing it using compasses? and then measuring the angles is there another way?

Crap im failing this lol

 

dont you have a math book and take notes in class?

im also in geometry and know #3 which is common sense to those that have worked with angles in math.

left side= 7cm
right side= 8cm
bottom =12cm

the top angle would be the largest angle because the bottom is the longest side which means the top angle needs to split more to make it connect.if you draw it out and used a protractor to measure it than you will see the top angle is


edit-- tr1gg4, a compass is the things you use to draw a circle not a triangle and you dont measure angles with a compass

 

actually .... if u do geometry u can draw very accurate triangles with compasses

by positioning a the compas to the required lenghts... you will get angle sizes to a accurate degree.
Its called construction - and i believe u will learn about it in the next 3 years... (LOL) heres a guide:

i jsut clearly said i was in geometry... wow......

 

ok posted the guide for you.. if your in geometry U SHOULD in theory know this.

 

Just ask your teacher if you can stay after school for extra help, and if that doesn't work ask your parents or an older sibiling, I'm only in algebra so i cant help you. Good luck though.

EDIT: Just noticed that this is due tomorrow, google "math help" and look up the unit your on.

 

I so cant be asked...
This isnt even a course... its like an additional course ontop of the compulsary course.. and im driven to to well - but i forgot everything.. and need the answers so she doesnt mark me down.....

and the thing is - this is long and difficult shit... she screwed at me once (teacher) and im not coming up to her for another screw. trust me...

easier said than done.

Besides i have a french speaking exam tomorow.. which i havnt looked at since Novemebr
and i have to redo my statistics coursework by Friday lunchtime ... it takes 3 weeks to do by working 3/4 hours a day on it.....

IM FUCKED. so yeh... help overnight would help..

 

Meh, we've covered most of this, but it's been a while and I didnt pay much attention.

Umm on number one just graph the equation with a graphing calc and find the slope of the tangent line at 3 and go from there.
