If AD perpendicular to BC , prove that AB² + CD² = BD² +AC²

Answer»

To Prove :-

$\leadsto\sf\: AB {}^{<klux>2</klux>} + CD {}^{2} = BD {}^{2} + AC {}^{2}$

SOLUTION:-

From triangle ADC , we have

$\leadsto \sf \: AC {}^{2} = AD {}^{2} + CD {}^{2} \longrightarrow(Pythagoras \: therom ) \longrightarrow(<klux>1</klux>)$

From triangle ADB , we have

$\leadsto \sf \: AB {}^{2} = AD {}^{2} + BD {}^{2} \longrightarrow(Pythagoras \: therom ) \longrightarrow(2)$

Subtracting (1) from (2), we have

$\leadsto \sf \: AB {}^{2} - AC {}^{2} = BD {}^{2} - CD {}^{2} \\ \\ \sf \: (or)\\ \\\leadsto \sf \: AB {}^{2} + CD {}^{2} = BD {}^{2} +AC {}^{2}$

25.	The figure formed by Joiningthe mid points of the consecutiveSides of quadrilateral lateral is.
Answer» Answer: Required Answer:- We KNOW that metals react with water to release Hydrogen gas (H2). Sodium and Calcium, both are metals. Hence, Hydrogen is released in both cases. Now let's see, Why the above phenomenon occurs?? Case 1: Sodium + Water Sodium is a very reactive metal. It reacts with water vigorously because water is the reagent here. As a result, Hydrogen gas is released. The reaction is highly exothermic and violent, hence releases a LOT of heat. This causes the hydrogen to burn and catch fire because hydrogen is a COMBUSTIBLE gas. Case 2: Calcium + Water Calcium is LITTLE less reactive as COMPARED to Sodium. The reaction of calcium and water is little less violent and hence the heat is released is not sufficient enough to burn the hydrogen released. Hence, when calcium metal is added to water the gas evolved dose not catch fire..............

Check whether 1 and 3/2 are the roots of the equation 2xsquare-5x+3

Answer»

Answer:

Yes.1 and 3/2 are roots of 2x²-5x+3

Step-by-step explanation:

Let f(X)=2x²-5x+3.

For any polynomial f(X) a NUMBER ß is said to be a root if f(ß)=0

so f(1)=2(1)²-5(1)+3

= 2-5+3

=5-5

=0

and f(3/2)=2(3/2)² -5(3/2)+3

=2(9/4)- 15/2 + 3

=(9-15)/2+3

= -6/2 + 3

= -3+3

=0

Answer» Let the length and the breadth of the rectangle be (x+6) and x respectively. Area of the rectangle = PRODUCT of length and breadth or, x (x+6) = 112 or, x^2 + 6X - 112 = 0 Splitting the middle term here, we have : x^2 + 14x - 8x - 112 = 0 or, x ( x + 14 ) - 8 ( x + 14 ) = 0 or, ( x + 14 ) (x - 8) = 0 or, x = 8 [ The value x = -14 is rejected SINCE the breadth cannot be a negative quantity) Thus, length = x + 6 = 14 cm I hope it helps you plzzz mark me has brainliest

Page :9. length of a rectangle is 6cm more than itswidth. if its length and breadth of the origingsRectangle.

Answer»

Let the length and the breadth of the rectangle be (x+6) and x respectively.

Area of the rectangle = PRODUCT of length and breadth

or, x (x+6) = 112

or, x^2 + 6X - 112 = 0

Splitting the middle term here, we have :

x^2 + 14x - 8x - 112 = 0

or, x ( x + 14 ) - 8 ( x + 14 ) = 0

or, ( x + 14 ) (x - 8) = 0

or, x = 8 [ The value x = -14 is rejected SINCE the breadth cannot be a negative quantity)

Thus, length = x + 6 = 14 cm

I hope it helps you plzzz mark me has brainliest
