Here, ∡BOT = 80o and ∡BAT = 26o, ∡ABO = 90o  [ Since, radius OB is perpendicular to tangent AP.] In quad.ABOT,  ∡BOT +   ∡BAT + ∡ATO + ∡ABO  = 360o, [ Since, sum of angles of a quad.] or,  .....

If simply you want to enlarge the volume by scale factor by 2, it will be 2 x 8cm3 = 16cm3. If you want to enlarge the each siedes by 2,  New sides will be length of 2 x 2cm = 4cm.   [ Since, V =  a3 ⟹ a .....

Lumbini is one of the world's most important spiritual sites of Nepal. If we talk about Lumbini, Buddha the light of Asia comes in our mind. Definitely, Lumbini is the birthplace of Buddha. Mayadevi Temple where Buddha was born is one of the .....

Here,  LHS = tanA. cosecA. SecA - 1  Using formula tanA=sinA/cosA, & cosecA=1/sinA , we get       = SinA/cosA .1 / sinA . .....

Here, Sum of angle in radian and degree is 611/21.  Or, pc + po = 1282/21 Or, (p . 180/π)o + po = 1282/21 [ Since, 1c = 180/πo] Or, p[ 180 . 7/22 + 1] = 1282/21   [ Since, π = 22/7.] Or, p[ .....

Here, T1(x, y) = (x + 5, y - 2) and T2(x, y) = (x - 3, y + 1), Now, we have formula,  T1T2(x, y) = T2T1(x, y) = T1 + T2                                .....

Here, LHS = ( 1 + tan2A)/tan2A       Using the relation, 1 + tan2A = sec2A and tanA = sinA / cosA, we get = sec2A / ( sin2A/cos2A) = 1/cos2A . cos2A / sin2A [ Since, secA = 1/cosA.] = 1/sin2A = coese2A        .....

Here, combine translation of 45 & ab is    = 45+ ab = a+4b+5  [ Since, T1oT2 = T1 + T2.] We know, Translation vector = Image - .....

Here,  First case,  Object = P(-3, 5) Image = P'(a, b) Translation vector = (2, 3). We know,       Image = Object + Translation vector  or, (a, b) = ( -3, 5) + (2, 3) or, (a, b) = ( -1, 8)    .....

Here, LHS = (cosec a +1)/ (cosec a -1) Using relation cosec a = 1 /sin a, we get = (1 / sin a +1)/ (1 / sin a -1)  Now taking LCM, = [ (1 + sin a)/sin a] / [ ( 1 - sin a)/sin a] =  (1 + sin a)/ .....

LHS = sec4A - sec2A         = sec2A( sec2A - 1)    [ Taking sec2A common.]         = ( tan2A + 1) tan2A    [ Since, sec2A = 1 + tan2A & sec2A - 1 = tan2A. Now open bracket and .....

b)  Given by the question Primary coil = 110  secondary coil = ? Primay voltage = 220 V Secondary voltage = 30 V By using formula  Vs / Vp = Ns / Np By using this formula you can solve .....

Here, LHS =  {(1- tan a )/(1 - cot a )} 2 = (1 - tan A)2 / (1 - cot A)2 = (1 - tan A)2 / [(tan A - 1) / tan A]2   [ Since, cotA = 1/tanA.]  Simplifying we get, = (1 - tan A)2 / [(tan A - 1)2 / .....

Here, LHS = (Sec2 A - 1) / (1+tan2A) Using (Sec2 A - 1) = tan2A &  (1+tan2A)= sec2A, we get = tan2A/sec2A = sin2A/cos .....

.....

Here, LHS = ( sina + cosa )2 [  Placing the formula, ( a+b )2 = a2 + 2ab + b2.  ] = sin2a + 2sina.cosa + cos2a = sin2a + cos2a + 2sina.cosa = 1 + 2sina.cosa [ Since, sin2a + cos2a = 1 ] RHS = 1 + 2sina.cosa Hence, LHS = .....
