ANSWER

ABCD is a rhombus. Show that AC bisects angle A as well as angle C and diakonals bisect angle B as well as angle D

Posted by Utkarsh Star 5 years, 10 months ago

CBSE > Class 09 > Mathematics

2 answers

Sia ? 5 years, 10 months ago

Given: ABCD is a rhombus

In $\triangle$ ABC and $\triangle$ ADC,
AB = CD [Sides of a rhombus]
BC = DA [Sides of a rhombus]
AC = AC [Common]
$\therefore$ $\triangle$ ABC $\cong$ $\triangle$ ADC [By SSS Congruency]
$\therefore$ $\angle$ CAB = $\angle$ CAD And $\angle$ ACB = $\angle$ ACD
Hence AC bisects $\angle$ A as well as $\angle$ C
Similarly, by joining B to D, we can prove that $\triangle$ ABD $\cong$ $\triangle$ CBD
Hence BD bisects $\angle$ B as well as $\angle$ D

find k if -2 is zero of polynomial 4x^2-x+k

Posted by Priya Kalra 5 years, 10 months ago

CBSE > Class 09 > Mathematics

2 answers

Priya Kalra 5 years, 10 months ago

x = -2
f(x) = 4x²-x+k
4(-2)² - (-2)+ k = 0
4(4) + 4 + k = 0
16 + 4 + k = 0
20 + k = 0
k = -20

You have written 4 but I think here must be 2 instead of 4

Yogita Ingle 5 years, 10 months ago

x = -2
f(x) = 4x²-x+k
4(-2)² - (-2)+ k = 0
4(4) + 4 + k = 0
16 + 4 + k = 0
20 + k = 0
k = -20

Six rational between 7and 9

Posted by Mayank Zade 5 years, 10 months ago

Sia ? 5 years, 10 months ago

We know that there are infinite rational numbers between any two numbers. A rational number is the one that can be written in the form of $\frac{p}{q}$ , where p and q are integers and $q \ne 0$ We know that the numbers all lie between 3 and 4. We need to rewrite the numbers in $\frac{p}{q}$ form to get the rational numbers between 3 and 4. So, we cover it in $\frac{p}{q}$

$\eqalign{ & {7 \over 1} = {7 \over 1} \times {{10} \over {10}} = {{70} \over {10}} \cr & {9 \over 1} = {9 \over 1} \times {{10} \over {10}} = {{90} \over {10}} \cr}$

So any six number between ${{70} \over {10}},{{90} \over {10}}$ will be the answer example ${{71} \over {10}},{{73} \over {10}},{{74} \over {10}},{{75} \over {10}},{{77} \over {10}},{{78} \over {10}}$
