x+3x=24 is right answer

x+3x = 24 is correct answer

please second step describe

I am not understand second step

Secθ+tanθ=p ----------------------(1)∵, sec²θ-tan²θ=1or, (secθ+tanθ)(secθ-tanθ)=1or, secθ-tanθ=1/p ----------------(2)Adding (1) and (2) we get,2secθ=p+1/por, secθ=(p²+1)/2p∴, cosθ=1/secθ=2p/(p²+1)∴, sinθ=√(1-cos²θ)=√[1-{2p/(p²+1)}²]=√[1-4p²/(p²+1)²]=√[{(p²+1)²-4p²}/(p²+1)²]=√[(p⁴+2p²+1-4p²)/(p²+1)²]=√(p⁴-2p²+1)/(p²+1)=√(p²-1)²/(p²+1)=(p²-1)/(p²+1)∴, cosecθ=1/sinθ=1/[(p²-1)/(p²+1)]=(p²+1)/(p²-1) Ans.

that's question answer is=43

0° is the correct answer of the given question

sec x-sinx=1/cosx-sinx1=sinxcosx

solution:-we know that Area of circle = πr²andin a rectangle length is great than it's breadth [ a> b] andwe can only draw a circle inside a rectangle with circle's diameter equal to breadth.

=> d = breadth of rectangle = b

=> 2r = b => r = b/2 Andthe Area of circle with radius (b/2) is

= πr² = π×(b/2)²

=> b²π/ 4 sq. unit.

8780.93

= 878093*10^-2

let. length be l and breadth be Bso according to question B+14=lnow perimeter=2(l+b/)160=2(b+14+b)80=2b+1426=66b=33cmhence l=33+14=47cm

As 1=sec^2-tan^2LHS sec+tan - (sec^2 - tan^ 2)/tan -sec + 1

take common sec + tan (1-sec + tan)/tan-sec+1

sec + tan

1/cos + sin/cos

1+sin/cos

multiply numerator and denominator by 1-sin

we get

1-sin^2/cos-cos sin

take cos common from denominator and 1-sin^2 is cos^2

cos^2/cos(1-sin)

cos/1-sin = RHS

Suppose you have a ∆ABCAll the exterior angles will be equal to(180-A)°(180-B)°(180-C)°respectively (Angles on the same line) so if you sum it up it will be equal to 540 - (A+ B + C )And by angle sum property A+B+C = 180°Therefore Sum = 540 - 180 = 360

a^4+2a^2b^2+b^4=(a^2)^2+2(a^2b^2)+(b^2)^2=(a^2+b^2)^2

Diameter of largest circle that can be cut is 7cm. (see picture)So radius = 7/2 = 3.5m

Area of circular part is πr^2=22/7*3.5*3.5=22*0.5*3.5=38.5m^2
