In `triangleABC` angleA is four times to B and C is five times to B . Find the three angles.

In triangle ABC , if angle A = 3 angle B and angle C = 2 angle B . Find all the three angles of triangle ABC .

Supplementary of an angle is three times the angle then the angle is

If angle A and angle B are conjugate angles and angleA=angleB find the two angles.

Let A=2hati+hatj-2hatk and B= hati+hatj . If C is a vector such that A.C=|C|,|C-A|=2 sqrt2 and the angle between A times B and C is 30^@ , then the value of |(A times B) times C| is

In /_\ABC , angleA=30^@, angle B=45^@ find angle C

Two wires A and B have equal lengths and are made of the same material but diameter of A is twice that of wire B. Then for a given load a) The extension of B will be four times that of A b) The extensions of A and B will be equal c) The strain in B is four times that in A d) The strains in A and B will be equal

Given that a,b,c are the sides of a triangleABC which is right angled at vertex C, then the minimum value of: (c/a + c/b)^(2) is:

If a and b are unit vectors and a xx b = 1 , then the angle between a and b is
