What is the ASA congruence rule of triangles, where A and S represents angle and side of triangle respectively?
401 06481883062f8ada03553507fIn △ABC, D and E are points on sides AB and AC, such that DE||BC. If AD=x+3, DB=2x-3, AE=x+1 and EC=2x-2, then the value of x is
402 0648044cce72c4684a1e52f47If C1, C2 be the centres of rwo circles and r1, r2 be the respective radii such that the distance between the centres is equal to the sum of the radii of the two circles, find the number of common tangents.
