Here No. of bricks = N = 2400 Volume of wall = V = 15m x 6m x 20/100 m = 180 cubic.m We know, N = volume of wall / volume of brick or, volume of brick = Volume of wall / N = 180/ 2400 = 0.075 cubic .....
Here, sin 105∘ = sin (60∘ + 45∘) = sin60∘cos45∘ + cos 60∘ sin 45∘ [ using: sin(A + B) = sinAcosB + cosAsinB] = (√3/2) x (1/√2) + (1/2) x (1/√2) = .....
We have given two equation of diameters, x + y = 5 and 2x - y = 1. Adding these, we get, x + y = 5 2x - y = 1 -------------- 3x = 6 ====> x = 2. Put, x = 2 in frist equation, 2 + y = 5 ==> y = 3. Hence centre of circle is ( .....

As an electric current flows along the wires from a powerhouse, it loses energy. A large current loses much more energy than a small current. So, a large current has to be converted into small current to prevent losing more energy. Hence, .....
Let the Marked Price(MP) = Rs. x. 1st condition: Selling at MP, So, SP1 = MP And, P% = 20%. So, CP = SP*100/( 100 + P%) = x(100)/(120) = 5x/6. Therefore, CP = Rs. 5x/6. Again, 2nd condition: D% = 5% And, Profit(P) = Rs. 180 So, SP .....
From LHS, 4cos.(60°+A).sin (30°+A).cos A = 4(cos60.cosA - sin60sinA)(sin30cosA + cos30sinA).cosA [ using: cos(A + B) and sin(A + B)] = 4{(1/2).cosA - √3/2sinA}{(1/2).cosA + (√3/2)sinA}.cosA = 4 x 1/4 (cosA .....
The movie is based on the true story of the ill-fated 13th Apollo mission bound for the moon. The qualities were never demonstrated more dramatically than in the flight of the 13th Apollo mission in April 1970, when an oxygen tank exploded en .....

Here, sin 3A = cos 7A or, sin 3A = sin (90∘ - 7A) [ cos(90∘ - A) = sin A] So, 3A = 90∘ - 7A or, 10A = 90∘ or, A = 90∘/10 or, A = .....
Here, sin 2A = cos 3A or, sin 2A = sin (90∘ - 3A) [ cos(90∘ - A) = sin A] So, 2A = 90∘ - 3A or, 5A .....
