What is the perimeter of a triangle ABC With Vertices A(-1,3) B(2,3) C (-1,-3)

Mathematics
1 answer:
KATRIN_1 [288]3 years ago
3 0

Answer:

15.71

Step-by-step explanation:

Length AB =  sqrt ( (3-3)^2 + (2- - 1)^2) =  sqrt9 = 3

Length BC =  sqrt ( (-3-3)^2 + ( -1-2)^2) =  sqrt  45

Lemgth CA =  sqrt( 6^2) + (-1 - -1)^2 = sqrt 36 = 6

Perimeter = 3 + 6 + sqrt45

= 15.71

Which two numbers on the number line have an absolute value of 1.75? Select the location of both numbers on the number line
hram777 [196]

Solution

             To    find   Which two numbers on the number line have  sn  

            absolute value of 1.75  .

            Absolute   value   means    " how  far   a  number    is   from  

            zero "  .

           "1.75"    is    1.75   away   from   zero  .

           and  " -1.75"   is  also   1.75    away   from  zero  .

          i.e

               |  0  - 1.75 |   =   1.75

              |  1.75 - 0 |  =  1.75  

           So ,  the  absolute   value  of   "1.75"    is  1.75  

          similarly  , absolute  value  of  "1.75"   is   1.75  .

          Hence  , the  two  numbers   are   -1.75  and  1.75  .

The second side of a triangular deck is 4 feet longer than the shortest side. The third side that is 4 feet shorter than twice t
Svetlanka [38]

The second side of a triangular deck is 4 feet longer than the shortest side

(s+4) = the 2nd side

and a third side that is 4 feet shorter than twice the length of the shortest side.

(2s-4) = the 3rd side

If the perimeter of the deck is 48 ​feet, what are the lengths of the three​ sides?

s + (s+4) + (2s-4) = 48

Combine like terms

s + s + 2s + 4 - 4 = 48

4s = 48

s = 48/4

s = 12 ft is the shortest side

I'll let you find the 2nd and 3rd sides, ensure they add up to 48

Hope this helps!
