A regular polygon with n sides is such that the angle subtended by its sides at its centre is 12 more than the angle subtended by an (n + 1)-sided regular polygon. If the area of the circle (circum-circle) which inscribes the n-sided polygon is 3850 mm2, then:(Given π = 22/7 and sin 540 = 0.8 and cos 540 = 0.6)
Two circles with radii 3 units and 8 units touch each other externally. Three common tangents are drawn to these two circles. Find the area of the triangle enclosed by these three tangents.
If the abscissa of the point of intersection of the lines 4x + 5y = 20 and y = mx + 3 is an integer, then the number of positive integral values for m are:
