Answer:
Step-by-step explanation:
In this problem, we have:
H = 452 m is the height of the Petronas tower
h = 1.75 m is the height of the woman
d = 120 m is the distance between the woman and the base of the tower
First of all, we notice that we want to find the angle of elevation between the woman's hat the top of the tower; this means that we have consider the difference between the height of the tower and the height of the woman, so
Now we notice that 
and 
are the two sides of a right triangle, in which the angle of elevation is 
. Therefore, we can write the following relationship:
since
H' represents the side of the triangle opposite to
d represents the side of the triangle adjacent to
Solving the equation for , we find the angle of elevation:

The conditional, <span>If four points are non-coplanar, then they are non-collinear, </span>is true:
This is, coplanarity is a necessary condition to be collinear.
The converse, <span>If four points are non-collinear, then they are non-coplanar, is false.
A counterexample that disproves this statement is the 4 vertices of a paralelogram, of course they are in a same plane and are not collinear.

Answer:
(1/3) weeks worth of pay.
Step-by-step explanation:
Keith has 3(1/12) weeks worth of pay in a wallet.
Keith has 3(5/12) weeks worth of pay in the bank.
How many more weeks of pay is in Keith's bank than Keith's wallet?
The number of weeks more of pay in Keith's bank than Keith's wallet
= (Number of weeks worth of pay in the bank) - (Number of weeks worth of pay in the wallet)
= 3(5/12) - 3(1/12)
= (4/12) = (1/3) weeks worth of pay.
Hope this Helps!!!
