WebAnswer (1 of 2): a+b =45 (I think it is 45°) tan(a+b) = tan 45° => (tan a + tan b)/(1 - tana.tanb) = 1 => tan a + tan b = 1 - tana.tanb => tan a + tan a.tan b +tan ...WebStep 1: Compare the tan (a - b) expression with the given expression to identify the angles 'a' and 'b'. Here, a = 60º and b = 45º. Step 2: We know, tan (a - b) = (tan a - tan b)/ (1 + tan a·tan b) ⇒ tan (60º - 45º) = (tan 60º - tan 45º)/ (1 + tan 60º·tan 45º) since, tan 60º = √3, tan 45º = 1most motivational hip hop songs
