Rampur Sarpanch requested one of his villager to donate a 6m wide land adjusted to his 132.8m long side of his right triangular

plot outside the village . The other sides of the plot is 123m and 50m .On his donated land , the Sarpanch wants to construct a link road which provides the connectivity with the other villages and towns . The villager agreed at once . I) Find the area of the triangular plot remaining with the villager . Ii) What are the values involved here ?

Answer:

Area of the remaining triangle with the villager is 1243.13 m²

Step-by-step explanation:

Triangle ABC is the triangular plot of a villager shown in the figure attached.

Sarpanch requested the villager to donate land which is 6 m wide and along the side AC which measures 132.8m.

Other sides of the plot has been given as AB = 50m and BC = 123 m.

Now area of this land before donation = \frac{1}{2}\times {\text{Height}}\times \taxt{Base}

= \frac{1}{2}\times (123)\times (50)

= 3075 square meter

After donation of the land the triangle formed is ΔDBE.

In ΔABC,

tan(ABC)=(\frac{AB}{BC})

tan(∠ABC) = \frac{50}{123}

                 = 0.4065

∠ABC = tan^{-1}(0.4065)

          = 22.12°

In ΔEFC,

tanC = \frac{EF}{CF}

0.4065 = \frac{6}{CF}

CF = \frac{6}{0.4065}

CF = 14.76 m

Since DE = AC - (CF + AG)

               = 132.8 - (2×14.76)

               = 132.8 - 29.52

               = 102.48 m

Now in ΔDBE,

sin(∠DEB) = \frac{BE}{DE}

sin(22.12) = \frac{BE}{102.48}

DB = 102.48×0.3765

     = 38.59 m

Similarly, cos(22.12) = \frac{BE}{DE}

0.9264 = \frac{BE}{102.48}

BE = 102.48×0.9264

     = 94.94m

Now area of ΔDBE = \frac{1}{2}(DB)(BE)

                                = \frac{1}{2}(38.59)(94.94)

                                = 1831.87 square meter

Area of remaining triangle with the villager = Area of ΔABC - Area of ΔDBE

= 3075 - 1831.87

= 1243.13 square meter

The game that is  used for the scenario above in terms of fair play is  using a balloon. Here, the player will hit the balloon.

<h3>What is the scenario under the balloon game?</h3>

The rule of play are:

This is a classic game with simple rules which are:

  • Each player to hit the balloon up and it bonce into the air but when one should not allow it to touch the ground.,
  • Players would be tied together in twos and they will juggle a lot of balloon and it have to be more than 1 balloon with one of their hands tied to their back.

A scenario of the worksheet game whose expected value is 0 is given below:

Assume that it costs about $1 for a player to play the billon game and as such, if  the player hits a balloon, they will be given $3. what can you say. Can you say that it this game is fair or not? and who has the biggest advantage.

Solution

Note that a  game is ”fair” if the expected value is said to be 0. When a player is said to hits a balloon, their net profit often increase by $4.  So when the player do not hit a balloon, it drops to $1.

(4)(0.313) + (-1)(0.313)

= 0.939 approximately

Thus, the expected value is $0.939 which tells that the game is fair.
