The second side of a triangular deck is 3 feet longer than the shortest side and a third side that is 3 feet shorter than twice
matrenka [14]

Answer:

Shortest Side = 20 feet

Second Side = 23 feets

Third Side = 37 feets

Step-by-step explanation:

Let the shortest side of the desk be x. Hence,

Second side = (x + 3) feets

Third side = (2x - 3) feets

Perimeter = 80ft

x + (x + 3) + (2x - 3) = 80

                          4x = 80

                             x = 20

Hence, Second side = (20 + 3) feets

                                  = 23 feets

Third side = (40 - 3) feets

                 = 37 feets

Hence<u>,</u><u> shortest side is 20 feets, Second side is 23 feets, Third side is 37 feets.</u>

A laser beam is transmitted with a "width" of .0008 degrees and
pickupchik [31]

Answer:

Object will be at a distance of 358098.6 km from the source

Step-by-step explanation:

We have given angle = 0.0008 degree =\frac{0.0008\times \pi }{180}=4.444\times 10^{-6}\pi

Radius is given = 2.50 km

Linear size of the object will be equal to diameter

So linear size = 2.5×2 = 5 km

We know that linear size =distance \times \Theta

So 5=d\times 4.444\times 10^{-6}\pi

d = 358098.6 km
