In a triangle `angleA=55^(@),angleB=15^(@),angleC=110^(@)`. Then `c^(2)-a^(2)` is equal to

In triangleABC , if angleA=45^(@), angleB=60^(@), angleC=75^(@) , then a:b:c =

In a triangle ABC, if /_A=55^(@) and /_B=15^(@), then c^(2)-a^(2) is equal to

In triangleABC , if angleA=55^@ , angleB=40^@ find angleC

In a triangleABC if angleA=72^(@) and angleB=63^(@) ,find angleC

In triangleABC, angleA=76^(@), angleB=48^(@) , then find angleC=?

DeltaABC , angleA+angleB=65^(@) , angleB+angleC=140^(@) ,then angleB is equal to

In a triangle,/_A=55^(@),/_B=15^(@),/_C=110^(@) and (c^(2)-a^(2))/(ab)=lambda then lambda=

In a triangleABC, angleA + angleB = 65^@ and angleB + angleC =140^@ . Then , angleB is equal to (A) 25^@ (B) 35^@ (C) 40^@ (D) 45^@
