30: -5, -2, | 2 |, | 3 |, 8
31: -7, -6, | 5 |, | -6 |, 8
32: -12, | 10 |, | -12 |, | -15 |, | -26 |
33: -17, | -11 |, | 20 |, 21, | -34 |
The absolute value turns a negative function into a positive one.
Example: | -24 | would become 24
If it is positive, it stays the same.
Example: | 14 | would simple be 14
width x-9 meters
(x²-x-72)÷(x+8)
= x-9
From the given ratio for we found the values are
Given the ratio for
We have to find the rest of trignometric functions:
can be written as
Comparing equations (1) and (2) we get
Equating the coressponding numerator and denominator respectively
Therefore and
We can find
(since )
To find :
