8.	ABCD is a parallelogram, if the two diagonalsareequal. Find the measure of LABC ,
Answer» Answer: Since ABCD is a PARALLELOGRAM. THEREFORE, AB=CD and AD=BC Thus, in △ABD and △ ACB, AD=BC BD=AC AB=AB So, by SSS CRITERION of congruence, △ABD≅△ACB Therefore, ∠BAD=∠ABC Now, AD∥BC and transversal AB INTERSECTS them at A and B respectively. Therefore, ∠BAD+∠ABC=180 o ∠ABC+∠ABC=180 o 2∠ABC=180 o ∠ABC=90 o Hence, the measure of ∠ABC is 90

8.

ABCD is a parallelogram, if the two diagonalsareequal. Find the measure of LABC ,

Answer»

Answer:

Since ABCD is a PARALLELOGRAM. THEREFORE,

AB=CD and AD=BC

Thus, in △ABD and △ ACB,

AD=BC

BD=AC

AB=AB

So, by SSS CRITERION of congruence,

△ABD≅△ACB

Therefore, ∠BAD=∠ABC

Now, AD∥BC and transversal AB INTERSECTS them at A and B respectively.

Therefore,

∠BAD+∠ABC=180

o

∠ABC+∠ABC=180

o

2∠ABC=180

o

∠ABC=90

Hence, the measure of ∠ABC is 90

चार समानुपाती पदों में मध्य पदों का गुणनफल 36 है। यदि बाह्य पदों में एकपद 3 हो, तो दूसरा बाह्य पद होगा-

Answer»

SOLUTION

GIVEN

The product of the middle terms is 36 AMONG the four proportional terms.

ONE of the extreme term is 3

TO DETERMINE

The second extreme term

EVALUATION

Let the four proportional terms are a , b , c , d

Now it is given that the product of the middle terms is 36 among the four proportional terms.

One of the extreme term is 3

∴ a = 3 & bc = 36

We have to find the value of d

Since four proportional terms are a , b , c , d

$\displaystyle \sf{ \frac{a}{b} = \frac{c}{d} }$

$\displaystyle \sf{ \implies \: ad = bc }$

$\displaystyle \sf{ \implies \: 3d =36 }$

$\displaystyle \sf{ \implies \: d =12}$

Hence the required second extreme term

= 12

22.

The base of a triangle is 8 cm. hypotenuse is 10cm.calculate its area

Answer»

ANSWER:

LET it's HIGHT be X cm

Step-by-step EXPLANATION:

$x { }^{2} = hypotaneuse^{2} - base ^{2}$

$x ^{2} = 10 ^{2} - 8 {}^{2}$

$x ^{2} = 100 - 64$

$x ^{2} = 36$

$x = \sqrt{36}$

$x = 6$

$area = 1 \div 2 \times bh$

$area = 1 \div 2 \times 8 \times 6$

$area = 24cm ^{2}$

Answer»

Given : Sum of the ages of father and son is 68.

After 8 years father will be thrice as old as son.

To Find: The present age (in years) of the son is

A) 18

B) 16

C) 15

D) 13

Solution:

Sum of the ages of father and son is 68.

Son age = S years

Father age = 68 - S years

After 8 years Son = S + 8

After 8 years father = 68 - S + 8 = 76 - S

After 8 years father will be thrice as old as son.

=> 76 - S = 3(S + 8)

=> 76 - S = 3S + 24

=> 4S = 52

=> S = 13

present age (in years) of the son is 13 Years
