Gwar [14]

Answer:

a photographer shines a camera light at a particular painting forming an angle of 50 degrees with a camera platform at the light

umka2103 [35]

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 :

$sin\theta = \frac{Perpendicular}{Hypotenuse}$

$sin50^{circ} = \frac{AC}{AB}$

$sin50^{circ} = \frac{AC}{55}$

$0.766*55 = AC$

$42.13= AC$

Thus the painting is 42.13 feet above the platform

If your away-from-home food bill was $520 in November 2012, what was it in November 2013?

son4ous [18]

If it was the exact spending as the previous year it would be $520 but doubled would be $1,040. Since there is not enough information in the problem I can not say for certain.
