Using the trignometric principles,sin (ACB) = AB/AC = 3/6 = 1/2Thus, angle ACB = 30 degreesand angle BAC = 90 - angle ACB = 60 degrees

x²+8x+15 = (x+3)(x+5)So, the value of x²+8x+15 is zero when x²+8x+15 = 0 i.e. x = -3 or x = -5.

Charged particles are fired into a magnetic field (perpendicular to the motion of the particles). Using Fleming’s left hand rule, a magnetic force acts centripetally – such that the charged particles e...
