Answer»

Answer:

Use distance formula

d=√(X2-X1)²+(Y2-Y1)²

Step-by-step explanation:

Here I will show you how to solve.

let's take example (I).

we have to find Distance AB.

x1 is 9

y1 is 3

these are coordinates of a point as we know(X,y)

similarly

x2 is 15 and Y2 is 11

now APPLY distance formula

AB=√(15-9)²+(11-3)²

=√36+64

=√100

=10.

If a and b are rational numbers find the value of a and b in each of the following equation root 3 + root 2 by root 3 minus root 2 is equals to a + b root 6

Answer»

ANSWER:

a=5 b=2

Step-by-step explanation:

(root 3 + root 2)/(root 3 - root 2) MULTIPLY NUMERATOR and denominator with (root 3 + root 2)

(root 3 + root 2)/(root 3 - root 2)

=((root 3 + root 2) * (root 3 + root 2)) / ((root 3 - root 2) *(root 3 + root 2))

=(root 3 + root 2)^2 /((root 3)^2 - (root 2)^2)

=( (root 3)^2 +(root 2)^2 + 2 * root 3* root 2 ) / (3-2)

=(3 + 2 + 2 *root 6) /1 here root 3* root 2=root (3*2)=root 6

=5 + 2 *root 6 = a + b root 6

comparing these two we get a=5 b = 2

25474.

In the figure given below, inscribedtriangle ABC is equilateral. find angle BDC and angle BECquick please, it's urgent

Answer»

ANSWER:

As we know that, Angles on the same segments are equal.

therefore, angle BDC = angle BAC

∆ABC is an EQUILATERAL triangle

so, angle BAC = 60°

hence, angle BDC = 60°

quadrilateral BECD is a concyclic quadrilateral.

therefore, angle BEC+ angle BDC = 180

or, angle BEC = 180-60 = 120°

Hence, Required angle BDC and angle BEC are 60° and 120° respectively.

25495.	How do I solve √ 7/ 3-√ 7 ? I know the answer is 7+3√ 7/2 but I dont know how I should solve.
Answer» Answer: Whenever there's a a-√b form of number in the denominator always multiply and DIVIDE by a+√b So, that the denominator BECOMES (a+√b)(a-√b) = a^2-b So, here, √7/3-√7 , multiplying and dividing by 3+√7 √7(3+√7)/(3+√7)(3-√7) = (3√7+7)/(3^2-7) = 7+3√7/2 Hope this helps you ! I hope you don't have any doubt in the steps ｡◕‿◕｡ Similarly, if you GET a+√b type number in denominator, multiply and divide by a-√b Further in a more complicated case if you ever get a number LIKE √p+√q type number in denominator then, divide and multiply by √p-√q, so that the denominator becomes p-q

25495.

How do I solve √ 7/ 3-√ 7 ? I know the answer is 7+3√ 7/2 but I dont know how I should solve.

Answer»

Answer:

Whenever there's a a-√b form of number in the denominator always multiply and DIVIDE by a+√b

So, that the denominator BECOMES

(a+√b)(a-√b) = a^2-b

So,

here,

√7/3-√7 , multiplying and dividing by 3+√7

√7(3+√7)/(3+√7)(3-√7) = (3√7+7)/(3^2-7) = 7+3√7/2

Hope this helps you !

I hope you don't have any doubt in the steps ｡◕‿◕｡

Similarly, if you GET a+√b type number in denominator, multiply and divide by a-√b

Further in a more complicated case if you ever get a number LIKE

√p+√q type number in denominator

then, divide and multiply by √p-√q, so that the denominator becomes p-q
