Toolbox,
Exercise 1D, Questions 4,6,8,9,10

I really really need to work on geometry...

[pi]

Can you post them up?

[Greatness]

Which exercise?? is it still from 1C?

[MBBS]

Fixed.

I don't have the pdf. Does anyone have worked solutions to the textbook >.< Would be infinitely appreciated.

Question 4   ('<' means angle)
Part a)
Triangle ABC is equilateral --> therefore <DAX = 30 (= <CBX)
Therefore triangle ADX = triangle BXC and both are isosceles
Hence, <ADX = 75
<CDX = 90 - 75 = 15
<DXC = 180 - (15 + 15) = 150

Part b)
From above, <CDX = <XDC = 15


Is that right?
 

[cohen]

Yes, those answers are right.
Im uploading the worked soloutions now for you.

[MBBS]

Correct

Hence, <ADX = 75   <-----

How did you find that? >.<

OMG, thankyou so so so so so so so so much!

[pi]

Correct

triangle ADX = triangle BXC and both are isosceles, that's the key

Let <ADX = x
30 + 2x = 180
x = 75

There you go, those questions were pretty hard for me aswell, but i managed to get up to 1H (or whatever one the ellipses, circles and hyperbolas were).
1d is probably the hardest exercise in chapter 1, the rest are fairly easy

FKN DU MA >.< Just got it then read what you wrote.

How could I be sooooo stupid >.<

ABSOLUTE LEGEND. How do I actually download it though >.< I want to have a copy that will work offline etc, not just online? Clicking Download just opens the file.
