Which equation can be used to find the answer? A playground with four sides has a perimeter of 73 ft. Three of the sides have lengths of 14 ft, 19 ft, and 25 ft. What is the length of the fourth side?

s – 14 + 19 + 25 = 73

s – 73 = 14 + 19 – 25

s + 14 + 19 + 25 = 73

s – 14 – 19 – 25 = 73

Considering that perimeter in the sum of all sides, we have:

Once the perimeter is 73 ft and tree of the sides were given:

The correct equation is:

Also,

(-5,-28)

i graphed to on desmos.

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
