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=

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

If an a triangle ABC,b=3c and C-B=90^(@), then find the value of tan B

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

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

If in a DeltaABC, angle B = (2pi)/(3) , then the cos A + cos C lies in

In any DeltaABC , prov "If in a "DeltaABC, /_C=90^(@)," then prove that sin"(A-B)=((a^(2)-b^(2)))/((a^(2)+b^(2)))

In a DeltaABC , if B=90^(@) , then tan^(2).(A)/(2) =
