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:
Answer:
000.611
Step-by-step explanation:
0.02×0.3055
=0.00611
So in three decimal places
000.611
Answer:
3x+10 = 2x+40
3x - 2x = +40 - 10
x = 30

Answer:
2.4 ft
Step-by-step explanation:
h = v/ pie r^2
The length and width of the rectangle is 362 m and 272 m respectively.
Step-by-step explanation:
Let the length be "x m".
then the width = x - 90 m
Perimeter = 2 x (length + width) ------------------------------(1)
Substituting Length and width value in the above equation (1), we get,
2 x (x+x-90) = 1268
or, 2x - 90 = 1268/2
or, 2x - 90 = 634
or, 2x = 634 + 90
or, 2x = 724
or, x = 724/2
= 362
Thus the length = 362 m
width = 362 - 90 m = 272 m
