SUPPOSE present age of Nisha = x years

-> Asha's age is 2 more than the square of nisha's age

Therefore, Asha's age = x^2 + 2

-> When Nisha GROWS as much as Asha

4. In AABC, D and E are points on the sides AB and AC respectively, such that DE || BC.If AD = 5 cm, DB = 8 cm and AC = 6.5 cm, find AE.

Answer»

ANSWER:

Converse of basic proportionality theorem :

If a line divides any two SIDES of a triangle in the same ratio then the line must be parallel to the third side.

SOLUTION :

1) Given : D and E are the points on sides AB and AC. AB = 12 cm, AD = 8 cm, AE = 12 cm, and AC = 18 cm.

To prove : DE || BC.

DB= AB - AD

DB = 12 - 8

DB = 4 cm

EC = AC - AE

EC = 18 - 12

EC = 6 cm

In ∆ABC,

AD / DB = 8/4 = 2

And, AE/EC = 12/ 6 = 2

so, AD / DB = AE/EC

Hence, DE || BC.

[By Converse of basic proportionality theorem]

2) Given : D and E are the points on sides AB and AC. AB = 5.6 cm, AD = 1.4 cm, AC = 7.2 cm, and AE = 1.8 cm.

To prove : DE || BC.

DB= AB - AD

DB = 5.6 - 1.4

DB = 4.2 cm

EC = AC - AE

EC = 7.2 - 1.8

EC = 5.4 cm

In ∆ABC,

AD / DB = 1.4 /4.2 = 1/3

And, AE/EC = 1.8/ 5.4 = 1/3

so, AD / DB = AE/EC

Hence, DE || BC.

[By Converse of basic proportionality theorem]

3) Given : D and E are the points on sides AB and AC. AB = 10.8 cm, BD = 4.5 cm, AC = 4.8 cm, and AE = 2.8 cm

To prove : DE || BC.

AD = AB – DB

AD = 10.8 – 4.5

AD = 6.3 cm

EC = AC – AE

EC = 4.8 – 2.8

EC = 2 cm

In ∆ABC,

AD / DB = 6.3/4.5 = 7/5 = 1.4

Hey friendsplease go to my profile ... go to question list their solve all the unanswered questions of Trigonometry pleasebut hereby too I'm giving u those two questionsI'm having the problem with calculationsno spam or I'll surely report

Answer»

ANSWER:

sin C = (Side opposite to ∠C)/(HYPOTENUSE) = AB/AC

cos C = (Side ADJACENT to ∠C)/(Hypotenuse) = BC/AC

tan C = (Side opposite to ∠C)/(Side adjacent to ∠C) = AB/AC = sin ∠C/cos ∠C

cosec C= 1/sin C = (Hypotenuse)/ (Side Opposite to ∠C) = AC/AB

sec C = 1/cos C = (Hypotenuse)/ (Side Opposite to ∠C) = AC/BC

cot C = 1/tan C = (Side adjacent to ∠C)/(Side opposite to ∠C)= BC/AB

Q => In the given figure, altitudes AD and CE of ∆ ABC intersect each other at the point P. Show that:(i) ∆AEP ~ ∆ CDP(ii) ∆ABD ~ ∆ CBE(iii) ∆AEP ~ ∆ADB(iv) ∆ PDC ~ ∆ BEC

Answer»

HERE IS YOUR ANSWER MATE.....;

Given that AD and CE are the altitudes of TRIANGLE ABC and these altitudes intersect each other at P.

(i) In ΔAEP and ΔCDP,

∠AEP = ∠CDP (90° each)

∠APE = ∠CPD (VERTICALLY opposite angles)

Hence, by AA similarity criterion,

ΔAEP ~ ΔCDP

(ii) In ΔABD and ΔCBE,

∠ADB = ∠CEB ( 90° each)

∠ABD = ∠CBE (Common Angles)

Hence, by AA similarity criterion,

ΔABD ~ ΔCBE

(iii) In ΔAEP and ΔADB,

∠AEP = ∠ADB (90° each)

∠PAE = ∠DAB (Common Angles)

Hence, by AA similarity criterion,

ΔAEP ~ ΔADB

(IV) In ΔPDC and ΔBEC,

∠PDC = ∠BEC (90° each)

∠PCD = ∠BCE (Common angles)

Hence, by AA similarity criterion,

ΔPDC ~ ΔBEC

Eight years ago Father age = x - 8 Since age = y - 8 so,x - 8 = 3(y - 8) x - 8 = 3y - 24 x = 3y - 16 ........(1) After 2 years, Father age = x + 2 Son age = y + 2 so, x + 2 = 2(y + 2) 3y - 16 + 2 = 2y + 4 y = 18 so, x= 3(18) - 16 = 54 - 16 = 38

26140.

Eight years ago the father age was three times that of his sons ,but two years hence the father age would be twice that of the sons .Find the present age of the father and the son.plzzzz help

Answer»

ANSWER:

LET father PRESENT age be x YEARS and son present age y years.

Eight years ago

Father age = x - 8

Since age = y - 8

so,x - 8 = 3(y - 8)

x - 8 = 3y - 24

x = 3y - 16 ........(1)

After 2 years,

Father age = x + 2

Son age = y + 2

so, x + 2 = 2(y + 2)

3y - 16 + 2 = 2y + 4

y = 18

so, x= 3(18) - 16 = 54 - 16 = 38

ABCD IS A QUASRILATERAL IN WHICH AD=BC AND angle DAB=ANGLE CBA.PROVE THAT TRIANGLE ABDis CONGRUENT TO TRIANGLE BACBAD=ACANGLE ABD=ANGLEBAC

Answer»

Answer:

Congruence of TRIANGLES:

Two ∆’s are congruent if sides and angles of a triangle are equal to the corresponding sides and angles of the other ∆.

In Congruent Triangles corresponding parts are always equal and we write it in SHORT CPCT i e, corresponding parts of Congruent Triangles.

It is necessary to write a correspondence of vertices correctly for writing the congruence of triangles in symbolic form.

Criteria for congruence of triangles:

There are 4 criteria for congruence of triangles.

SAS( side angle side):

Two Triangles are congruent if two sides and the included angle of a triangle are equal to the two sides and included angle of the the other triangle.

----------------------------------------------------------------------------------------------------

First use, SAS rule to show congruence of triangles and then use CPCT to show ii & iii parts.

Given:

In quadrilateral ABCD,

AD = BC &

∠DAB = ∠CBA

To Prove:

(i) ΔABD ≅ ΔBAC

(ii) BD=AC

(iii) ∠ABD = ∠BAC

Proof:

i)

In ΔABD & ΔBAC,

AB = BA (Common)

∠DAB = ∠CBA (Given)

AD = BC (Given)

Hence, ΔABD ≅ ΔBAC.

( by SAS congruence rule).

(ii) Since, ΔABD ≅ ΔBAC

Then, BD = AC ( by CPCT)

(iv) Since, ΔABD ≅ ΔBAC

Then , ∠ABD = ∠BAC (by CPCT)

THEREFORE, TRIANGLE ABD ≅ TRIANGLE BAC ( BY SAS)

THEREFORE, BD = AC (CPCT)

ALSO, ∠ ABD = BAC (CPCT)
