maria [59]

Given that,

The camera sights the stadium at a 7 degree angle of depression.

The altitude of the blimp i slide 300 m.

To find,

The line of sight distance from the camera to the stadium.

Solution,

If we consider a right angled triangle. Let x is its hypotenuse i.e. the line of sight distance from the camera to the stadium. Using trigonometry :

\sin\theta=\dfrac{P}{x}\\\\x=\dfrac{P}{\sin\theta}\\\\=\dfrac{300}{\sin7}\\\\=2461.65\ m

So, the line of sight is at a distance of 2461.65 m from the camera to the stadium.

A man sold 3 times as many tie dyed shirts as white shirts. He sold 196 shirts altogether. How many tie dyed shirts did he sell?
Ivanshal [37]
We solve this the following way:

tie dyed shirts = x
white shirts = y 

x = 3y

x + y = 196

3y + y = 196 (we substitute the x with the 3y in the main equation)

4y = 196 (divide this)

y =49

x = 147

The man sold 147 tie dyed shirts and 49 white shirts.
