In the ambiguous case, if `a, b and A` are given and `c_1, c_2` are the two values of the third `(c_1-c_2)^2 + (c_1+c_2)^2 tan^2 A` is equal to

If a , b ,\ A are given in a triangle and c_1a n d\ c_2 are two possible values of third side such that c_1^2+c_1c_2+c_2^2=a^2 , then A is equal to 30^0 (b) 60^0 (c) 90^0 (d) 120^0

If a,b and /_A are given in a triangle and c_(1),c_(2) are the possible values of the remaining side,then c_(1)^(2)+c_(2)^(2)-2c_(1)c_(2)cos2A is equal to:

In Delta ABC, a, b and A are given and c_(1), c_(2) are two values of the third side c. Prove that the sum of the area of two triangles with sides a, b, c_(1) and a, b c_(2) " is " (1)/(2) b^(2) sin 2A

If a, b and A are given in a triangle and c_(1), c_(2) are possible values of the third side, then prove that c_(1)^(2) + c_(2)^(2) - 2c_(1) c_(2) cos 2A = 4a^(2) cos^(2)A

If a,b,A be given in a triangle and c_(1) and c_(2) be two possible value of the third side such that c_(1)^(2)+c_(1)c_(2)+c_(2)^(2)=a^(2), then a is equal to

In a delta ABC, a,c, A are given and b_(1) , b_(2) are two values of third side b such that b_(2)=2b_(1). Then, the value of sin A.

In a Delta ABC, a,b,A are given and c_(1), c_(2) are two valus of the third side c. The sum of the areas two triangles with sides a,b, c_(1) and a,b,c_(2) is

In a DeltaABC , a,b,A are given and c_(1),c_(2) are two values of the third side c. The sum of the areas of two triangles with sides a,b, c_(1) and a,b, c_(2) is
