Answer:
(x, y) = (4, 0)
Step-by-step explanation:
It looks like you want to solve ...
Adding the two equations gives ...
2x = 8
x = 4 . . . . divide by 2
Then ...
y = 4 - x = 0
The solution is (x, y) = (4, 0).
_____
If you think about what you're seeing when you read the equations, you realize that adding or subtracting y gives the same result. Hence y=0 and x=4.
Answer:
The painting is 42.13 feet above the platform
Step-by-step explanation:
Refer the attached figure .
A particular painting forming an angle of 50 degrees with a camera platform .
∠ABC = 50°
We are also given that the light is 55 feet from the wall where the painting hangs
i.e. AB = 55 feet.
Now we are required to find how high above the platform is the painting. i.e. AC
So, we will use trigonometric ratio :
Thus the painting is 42.13 feet above the platform
