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:
g = 530. r = 364
Step-by-step explanation:
Let g = number of general admission tickets
let r = reserved tickets
4.50g + 6r = 4569
g + r = 894
Multiply second equation by -6
-6g - 6r = -5364
Add to first equation
-6g - 6r = -5364
4.5g + 6r = 4569
-——————————
-1.5g = -795. Divide by -1.5
g = 530
Substitute into equation
530 + r = 894
r = 364
Answer:
350.82
Step-by-step explanation:
To find the surface area, you must add up all of the areas of each shape of the prism in order to get the sum surface area.
The rectangle's area ():
The triangle's area ():
Now add up all the sides. (3 Rectangles, 2 Triangles.)
The total surface area is 350.82 cm squared.
