We can use trigonometry to solve the problem. First draw a picture of the situation to understand what is going on (See the attached photo).
Next, we can use the tangent function to solve for the height of the building:
Next, rearrange the problem to solve for h:
h = 39.356 ft

The surface area of the triangular prism is of 162 cm².
<h3>What is the surface area of a prism?</h3>
The surface area of a prism is given by the sum of all the areas of the prism.
This prism is composed by:
- One rectangle of dimensions 10 cm and 7 + 6 + 4 = 15 cm.
- Two right triangles, of sides 6 cm and 4 cm.
For a rectangle, the area is the multiplication of the dimensions, hence:
A1 = 10 x 15 = 150 cm².
For a right triangle, the area is half the multiplication of the sides, hence:
A2 = 0.5 x 6 x 4 = 12 cm².
Hence the surface area is:
A = A1 + A2 = 150 cm² + 12 cm² = 162 cm².

I think it is at 23 degrees (I am really sorry if I am wrong)
Answer:
432 tiles
Step-by-step explanation:
First, convert the dimensions of the table to inches.
There are 12 inches in a foot, so multiply 1.5 and 2 by 12.
1.5(12) = 18
2(12) = 24
So, the dimensions of the table in inches are 18 by 24.
Find the area of the table using the formula, A = lw
A = lw
A = (18)(24)
A = 432
So, the area is 432 square inches.
Since each tile is one square inch, the table will fit 432 of these.
So, Ravi will need 432 tiles.
