In right angled `triangleACB, angleC = 90^@`, AC = 3, BC = 4. Find the ratios sin A, sin B, cos A, tan B.

In right-angled DeltaABC , if angle B=90^(@) , AB = 6 , BC=8, then find AC.

In triangle ABC , /_B=90^@ and AB = BC. If AC = 2sqrt2 , then find AB and BC.

If in DeltaABC,angleB=90^(@) and angleC=theta , then write the ratios sin theta and tan theta

In a right angled DeltaABC, angleA = 90^@ and (5sin^2 B + 7 cos^2 C + 4)/(3 + 8 tan^2 60^@) = 7/27 and AC=3 . Find the perimeter of DeltaABC .
