A monument in the shape of a right triangle sits on a rectangular pedestarl that is 7 meters high by 16 meters long. The longest
Minchanka [31]

Answer: 70 meters

Step-by-step explanation:

Hi, since the situation forms a right triangle and a rectangle, we have to apply the Pythagorean Theorem (for the triangle)

c^2 = a^2 + b^2  

Where c is the hypotenuse of the triangle (the longest side) and a and b are the other sides.  

Replacing with the values given:  

65^2 = 16^2 + x^2  

4,225 = 256 + x^2

4,225-256 = x^2

3,969=x^2

√3,969 =x

63=x

We have calculated the missing side of the triangle, now we have to add the height of the rectangle:

63 +7 =70 meters

Feel free to ask for more if needed or if you did not understand something.

Considering this real-world scenario, find UV and RS and explain your reasoning as part of your answer.
Katen [24]

The length of UV and RS is 72.2in and 114 in respectively

<h3>Similarity theorem of triangles</h3>

From the given truss. you can see that:
VW = UR = RS = 57in

Get the length of RS

  • RS = UR + US
  • RS = 57 + 57
  • RS = 114 inches

To get the length of UV, we will use the expression

SU/UV = SR/RT

57/UV = 114/90

UV = 72.2in

Hence the length of UV and RS is 72.2in and 114 in respectively
