Step-by-step explanation:

The formula for a triangle is base x height x 1/2

The triangles on the top and bottom have a base and height of 6 and 12 so: 6x12x1/2= 36 There are 2 of them so: 36 + 36 = 72

The triangles on the sides have a base and height of 8 and 14 so: 8x14x1/2=56 There are also 2 of them so: 56 + 56 = 112

The formula for the area of a rectangle is length x width

The length and width of the rectangle is 6 and 8 so: 6 x 8 = 48

Now add up all of the areas: 72 + 112 + 48 = 232

A source of laser light sends rays AB and AC toward two opposite walls of a hall. The light rays strike the walls at points B an

____ [38]

Answer: 70 meters.

Step-by-step explanation:

Observe the figure attached.

The distance between the walls is:

$DE=AD+AE$

<em />

Both triangles are right triangles. Therefore, you can calculate the distance between the walls as following:

- Calculate the distance AD:

$cos\alpha=\frac{adjacent}{hypotenuse}\\\\cos(60\°)=\frac{AD}{60}\\AD=30m$

- Calculate the distance AE:

$tan\beta =\frac{opposite}{adjacent}\\\\tan(45\°)=\frac{40}{AE}\\\\AE=\frac{40}{tan(45\°)}\\\\AE=40m$

Therefore the distance between the walls is:

$DE=30m+40m=70m$
