length will be equal to the perimeter hence perimeter of a square is 4xside=4*60=240m

Given,Age of A = 19 yearsAge of B = 15 years

Let in x years product of ages will be 480

Then,(19 + x)*(15 + x) = 48019*15 + 19x + 15x + x^2 = 480x^2 + 34x - 195 = 0x^2 + 39x - 5x - 195 = 0x(x + 39) - 5(x + 39) = 0(x - 5)(x + 39) = 0x = 5, - 39

Negative value not possible

Therefore, on adding 5 to each 19 and 15 product will be 480

11+13+3!

3!=3×2×1=611+13+6=30so the answer is 11+13+3!

log 15=log(3×5)Using product law of logarithm we get log(3)+log(5)

As (a+b+c)2= a2+ b2+ c2+ 2(ab + bc+ ca)= 9a2+ 16b2+ 25c2+ 24ab + 40bc + 30ca

the answer is 15 centimetres

the answer is ( 3)15 centimetres .

perimeter of the triangle is sum of all the sides so (6+5+4)cm=15 cm

the answer of the question is (iii) 15 cm

PERIMETER OF TRIANGLE =SUM OF ALL SIDESO 6 + 5 + 4 CM = 15 CM

perimeter of a triangle is sum of all sides that is 6+5+4=15centimeters

the answer is 15 centimetres

The distance around a circular region is called it's circumference.

if radius of the circular region is given as R

Then circumference will be 2πR

One hour = 60 minutes4 hours = 60*4 = 240 minutes

4 hours 24 min= 240 + 24 = 264 minutes

(3) is correct option

1 hour = 60min4 hour = 4 X 60 = 2404 hour 24 min = 240+24 =264

if 1hour=60minut then 4 hour=4.60=240minut then 240+24=264minut

Given A = 30°

LHS: cos 2A= cos 2*30= cos 60°= 1/2

RHS: cos^2 A - sin^2 A= cos^2 30 - sin^2 30= (root(3)/2)^2 - (1/2)^2= 3/4 - 1/4= 2/4 = 1/2

Hence proved

We have to prove that Cos2A/1+sin2A=tan(π/4-A)

Solution:-As shown in attachment...

Formula used :Cos 2x = cos²x- sin²x Sin²x +cos² x =1Sin 2x = 2sin x cos x And (1-tan x)/(1+tan x) = tan (π/4 -x)please like the solution 👍 ✔️

LHS =cosA/(1+sinA) +(1+sinA)/cosA

={cos²A +(1+sinA)²}/cosA.(1+sinA)

={cos²A+1+sin²A+2sinA}/cosA.(1+sinA)

use sin²∅ +cos²∅ =1

=(1+1+2sinA)/cosA(1+sinA)

=2(1+sinA)/cosA(1+sinA)

=2/cosA

=2secA = RHS

bhai distance formula lga ke solve krdo n

The. distance between. the two point is. 2p-2q

p -q √2 is a write answer

2p-2q is the distance between two points A and B

(v+v)/distance speed

equal distance between points

the distance between.the two point is.2p-2q

2(p-q) and2(q-p)is the distance between both points .the value of both is same but sign is negative ,so we can neglact negative because the distance always measured in postive never be negative

(+/-)√2(p-q) this is your answer

√ (q+r-p-r)^2 + ( q-p)^2 = √2 • ( q-p )

The answer is p+q/2,q+p+2r/2

√2 p-q

square root over ( q-p)²+(q-p)²=1.414×(q-p)

it's like thisassume distance=x,x²=[p-q]²+[(q+r)-(p+r)]²x²=(p-q)²+(q-p)²x²=2(p-q)²x=√2(p-q)²

Use the distence formula of pint line

The answer will be √2(p-q).

distance between two point is (p-q)√2

underroot 2 (p-q) is the answer for the given question

use distance frula and then compare them

using distance formula

the answer is 2p-2q for the following question

(p - q)√2 unit is the correct answer

the distance between the two points is 2p-2qplz assign my answer as the best answer

LHS:sin(A + B)

= - cos (A + B + pi/2)

= - cosA cos(B + pi/2) + sinA sin (B + pi/2)

= cosA sin B + sin A cos B

= RHS

Hence proved

Ans :- Decius Brutus is a great flatterer. Heis more successful in persuading Caesar than Calpurnia because his argument appeals to Caesar’s pride.While Calpurnia wishes that Caesar stay at home after seeing horrible dreams, Decius Brutus interprets the dreams lucky and fortunate. According to him, they signify Caesar’s power and influence. He gives Caesar’s ego a boost. Caesar is totally carried away by his words and decides to go to the Capitol.

because both given are vertically opposite angle so ,x+x = 1382x = 138x = 69

cos2A = sin3A==> cos2A = cos(90 - 3A)

==> Either 2A = 90 - 3A or 2A = -(90 - 3A)==> 5A = 90 or 2A = -90 +3A==> A = 18 or A = 90. These are the solutions from 0 degrees to 360 degrees.

WhySin3A to cos(90-3A) to convert

So 2√5 =a+b√35 a= 0 2√5 = b √7. √5 b= 2/√7

x+x+29+x-17= 1803x= 197-293x= 168x= 56

x+x+29+x-17=1803x=197-29 3x=168x=56 answer

The sum of the angles are =180°So,x+(x+29)+(x-17)=180°3x+12=180°3x=180°-12°3x=168°x=168/3x=56°
