Let A(a, a), B(-a, -a) C{tex}\left( { - \sqrt 3 a,,\sqrt 3 a} \right){/tex}
{tex}AB = \sqrt {{{( - a - a)}^2} + {{( - a - a)}^2}} = \sqrt {8{a^2}} = 2\sqrt 2 a{/tex}
{tex}BC = \sqrt {{{( - \sqrt 3 a + a)}^2} + {{(\sqrt 3 a + a)}^2}} = 2\sqrt 2 a{/tex}
{tex}AC = \sqrt {{{( - \sqrt 3 a - a)}^2} + {{(\sqrt 3 a - a)}^2}} = 2\sqrt 2 a{/tex}
{tex}\therefore {/tex} AB = BC = AC = {tex}2\sqrt 2 a{/tex}
{tex}ar\Delta ABC = \frac{{\sqrt 3 }}{4} \times {(side)^2}{/tex}
{tex} = \frac{{\sqrt 3 }}{4} \times \left( {2\sqrt 2 a} \right)^2{/tex}
{tex} = 2\sqrt 3 {a^2}{/tex} sq. units

Database Management System (DBMS) is a collection of programs that enable users to create, maintain a database, and control all the access to the database. The primary goal of the DBMS is to provide an environment that is both convenient and efficient for users to retrieve and store information. The advantages of using DBMS for school are as follows:
- In school, DBMS is used to store the data about students, teachers, and any other related things at a centralised location.
- It provides security to the personal information of the school, stored in it.

Given: A circle with centre O. A tangent CD at C.
Diameter AB is produced to D.
BC and AC chords are joined, ∠BAC = 30°
To prove: BC = BD
Proof: DC is tangent at C and, CB is chord at C.
Therefore, ∠DCB = ∠BAC [∠s in alternate segment of a circle]
⇒ ∠DCB = 30° …(i) [∵ ∠BAC = 30° (Given)]
AOB is diameter. [Given]
Therefore, ∠BCA = 90° [Angle in s semi circle]
Therefore, ∠ABC = 180° - 90° - 30° = 60°
In ΔBDC,
Exterior ∠B = ∠D + ∠BCD
⇒ 60° = ∠D + 30°
⇒ ∠D = 30° …(ii)
Therefore, ∠DCB = ∠D = 30° [From (i), (ii)]
⇒ BD = BC [∵ Sides opposite to equal angles are equal in a triangle]
Hence, proved.

Given,
There are some dietary requirements of the staple food of the adolescent students of some schools.
To Find,
(1) 2 food items including one pulse and one cereal.
(2)The minimum cost of one pulse and one cereal.
(3) The formulated version of the corresponding linear programming problem.
(4)The problem graph,
Solution,
We can solve this mathematical linear programming problem using the method.
At first let's assume that the 2 food items be, Wheat and arhar dal or pigeon peas.
The rate of Wheat is Rs. 20 per kg and the rate of Arhar dal is Rs. 100 per kg.
So, we need to minimize the 100x+20y.
We know protein in arhar dal is 220gm / kg and in wheat 100gm/kg.
Carbohydrate in arhar dal is 630gm / kg and in wheat 760gm/kg.
Suppose the dietary requirements of adolescent students are as below,
- The requirement for protein is 60gm
- Carbohydrate is 1500gm.
So we can formulate our corresponding linear programming problem as follows,
Zminimize=100x+20y
Constrains are-
{tex}\begin{aligned} & 220 x+100 y \geq 60 \\ & 630 x+760 y \geq 1500 \text { and } \mathrm{x}, \mathrm{y} \geq 0 \end{aligned}{/tex}
Hence, the answers are as follows- The two food items including one pulse and one cereal are Wheat and Arhar dal/ pigeon peas. The arhar dal is Rs.100/kg and wheat is Rs. 20/kg. The linear programming problem is -Zminimize=100x+20y, Constrains are- {tex}\begin{aligned} & 220 x+100 y \geq 60 \\ & 630 x+760 y \geq 1500 \text { and } \mathrm{x}, \mathrm{y} \geq 0 \end{aligned}{/tex} and x,y{tex}\geq 0{/tex}
