" Man angleA And /_ B Low angle हो,जहाँ cos "A=cos B" ,तो Show that "/_A=/_B

If /_A and /_B are acute angles such that cos A=cos B . then show that /_A=/_B .

If /_A and /_B are acute angles such that cos A=cos B . then show that /_A=/_B .

if angleA and angleB are acute angles such that cos A = cos B , show that angleA=angleB .

In /_\ ABC and /_\ XYZ , if /_A and /_X are acute angles such that cos A = cos X then show that /_A = /_X .

If angle A and angle B are acute angles such that cos A = cos B , then show that angle A = angle B .

If angleA and angleB are acute angles such that cos A = cos B, then show that angleA = angleB

If angleA and angle B are acute such that cosA=cosB,then show that angleA=angleB

If angleA and angleB are acute angles such that cos A= cos B, then show then show that angleA=angleB .

If If and and are acute angles such that are acute angles such that then show that /_A=/_B

If A + B + C = pi "and" cos A = cos B cos C, "show that" tan B tanC = 2
