Answer:
X=30; Z=80; Y=70
Step-by-step explanation:
The straight lines equal 180 and you subtract 180 to 150 and 180 to 100 to get 30 and 80 and the inside of a triangle is 180 and you subtract 30 and 80 to 180 to get 70.
-3/5 they have opposite slopes so they would never touch but are parallel.
Answer: ![scale\ factor=230](https://tex.z-dn.net/?f=scale%5C%20factor%3D230)
Step-by-step explanation:
You need to analize all the information given in the exercise.
You know that the actual height of the T-rex on the projector lens is the following:
![actual\ height=2\ cm](https://tex.z-dn.net/?f=actual%5C%20height%3D2%5C%20cm)
The height of the projected T-rex is:
![projected\ height=4.6\ m](https://tex.z-dn.net/?f=projected%5C%20height%3D4.6%5C%20m)
Make the conversion from meters to centimeters:
![projected\ heigth=(4.6\ m)(\frac{100\ cm}{1\ m})\\\\projected\ heigth= 460\ cm](https://tex.z-dn.net/?f=projected%5C%20heigth%3D%284.6%5C%20m%29%28%5Cfrac%7B100%5C%20cm%7D%7B1%5C%20m%7D%29%5C%5C%5C%5Cprojected%5C%20heigth%3D%20460%5C%20cm)
Therefore, the scale factor will be:
![scale\ factor=\frac{projected\ heigth}{actual\ heigth}](https://tex.z-dn.net/?f=scale%5C%20factor%3D%5Cfrac%7Bprojected%5C%20heigth%7D%7Bactual%5C%20heigth%7D)
Finally, you must substitute values into the equation and then you must evaluate in order to find the scale factor of the projection. You get that this is:
![scale\ factor=\frac{460\ cm}{2\ cm}\\\\scale\ factor=230](https://tex.z-dn.net/?f=scale%5C%20factor%3D%5Cfrac%7B460%5C%20cm%7D%7B2%5C%20cm%7D%5C%5C%5C%5Cscale%5C%20factor%3D230)
