If in a `DeltaABC`, c = 3b and C - B = 90°, then tanB=

In a DeltaABC , if a =2, B = 60°and C =75°, then b=

If an a triangle A B C , b=3 c, a n d C-B=90^0, then find the value of tanB

If an a triangle A B C , b=3ca n d C-B=90^0, then find the value of tanB

In DeltaABC, if 2b =a+ c and A-C=90^(@), then sin B equal All symbols used have usual meaning in Delta ABC.]

In DeltaABC, a = 3, b = 4 and c = 5 , then value of sinA + sin2B + sin3C is

In DeltaABC, a = 3, b = 4 and c = 5 , then value of sinA + sin2B + sin3C is

In a DeltaABC if b =a (sqrt3-1) and /_C =30^@ then the measure of the angle A is

In a DeltaABC , sum (b + c) cos A=

In A DeltaABC , if a = 2 , b = 3 and sin A = 2/3 then angleB is (a) 90^(@) (b) 80^(@) (c) 110^(@) (d) 140^(@)

If in a DeltaABC,Delta = ( c + a - b) (a + b - c), then tan A is equal to
