If `A and B` are positive acute angles and `cos A = 1/7, cos B = 13/14`, then show that `A-B=60^0`.

If A and B are positive acute angles such that sin (A - B) =1/2 and cos (A + B) = 1/2 , then A and B are given by

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

If A,B,C are positive acute angles and tan A=4/7 and tan B=1/7,tan C=1/8 prove that A+B+C=45^@

If A,B,C are positive acute angles and tan A =4/7, tanB =1/7, tanC=1/8,"prove that" A+B+C = 45^(@)
